Swift Cycle 14 Results

The lists below contain the proposals recommended by the Cycle 14 Peer Review panel. Note that in addition to the accepted programs below, ToO requests for exceptional transients will continue to be possible through the Swift ToO web site, even for ToOs not accepted into the GI Program. The decision on whether or not to observe a ToO of either category will be made by the Swift Principal Investigator.

PIs of Cycle 14 proposals for observation: Please note that the ROSES 2017 Appendix D.5 "Swift Guest Investigator Cycle 14" states:

"It is the responsibility of the Principal Investigator (PI) of an accepted ToO to alert the Swift Observatory Duty Scientist when trigger conditions for their accepted ToO have been met. This is done through the Swift ToO Request Form at https://www.swift.psu.edu/secure/toop/request.php. It is highly recommended that ToO proposers register as Swift ToO users in advance at https://www.swift.psu.edu/secure/toop/too_newuser.php. Registration is required in order to submit a ToO Request."

"ToO proposals must have an astrophysical trigger. Once the trigger criteria have been met for an approved target, the PI should check if the target location is more than five hours in RA from the Sun and more than 20 degrees from the Moon before requesting Swift observations (http://heasarc.gsfc.nasa.gov/Tools/Viewing.html)."

"Accepted Cycle 14 ToO proposals may be triggered until March 31, 2019."

KEY PROJECT  "CONTINUING A SWIFT LEGACY: THE MONITORING CAMPAIGN OF THE GALACTIC CENTER"

The center of our Galaxy has been monitored with the Swift/XRT almost every day since 2006. The high cadence provides excellent means to capture X-ray flares from Sgr A*, and to study the accretion properties of 16 transient X-ray binaries. We propose to continue this Swift legacy program in cycles 14-15 and request daily 1-ks observations that amount to 490 ks of total exposure time. Our main objectives are to: 1) collect and study new flares from Sgr A*, 2) to test if the gaseous object G2 is disrupted and feeds matter to the supermassive black hole, and 3) to apply accretion models to very-faint X-ray binaries. This program is of high scientific value for a broad community.

KEY PROJECT  "INTENSIVE SWIFT/GROUND-BASED/HST ACCRETION DISK REVERBERATION MAPPING OF THE "BARE" ACTIVE GALACTIC NUCLEUS FAIRALL 9"

Led by Swift, Intensive Disk Reverberation Mapping (IDRM) is providing new insights into the physics of active galactic nuclei (AGN) and strongly challenging the standard thin accretion disk/reprocessing model of AGN central engines. Fairall 9 is a "bare" AGN with very low absorption, simplifying the physical interpretation. This plus the fact that it is observable by Swift throughout the year makes it an ideal IDRM target. We request 650 x 500 s daily visits, for which we will also obtain ground-based ugriz at a similar cadence to measure the interband lag-wavelength relation to perform echo mapping on the disk. We will also request HST monitoring in year 2 of the campaign to measure the lag spectrum and disentangle contributions to the lags from the disk and broad line region.

KEY PROJECT  "SUPERNOVA KEY PROJECT: SWIFT RESPONSE TO NEARBY SUPERNOVAE"

Swift has proven itself to be an extraordinary supernova (SN) observatory. The clearest application of Swift’s unique strengths is obtaining very early UV and X-ray data on young SNe to constrain their progenitor systems. As part of this key project, we propose a two-year follow-up program to rapidly observe all of the nearest (distance<35 Mpc or roughly z<0.008) extragalactic transients (mostly SNe). The quick-response, distance-limited program we propose will detect any UV-bright radiative cooling following the shock breakout from core-collapse SNe and shocked companions from Type Ia SNe. Just as importantly, we will constrain the fraction of events for which it is not seen.

KEY PROJECT  "A COMPREHENSIVE, MULTI-WAVELENGTH SURVEY OF COOL STAR ACTIVITY"

M-dwarfs are abundant and frequently host small planets. In the coming decade, efforts to detect and characterize rocky planets will focus on M-dwarfs. However, these stars are known to be highly magnetically active, thus planets they host are subjected to significantly more radiation than we experience from the Sun; just how much this affects their habitability is unsettled. We propose an ambitious multi-year, multi-instrument campaign to monitor M-dwarfs with ages from 10 Myr to 10 Gyr. X-ray, UV, and radio observations will be combined with simultaneous high-precision optical data from the Transiting Exoplanet Survey Satellite (TESS). The combined data will provide a complete picture of M dwarf activity, enabling us to identify environments conducive to harboring habitable planets.

KEY PROJECT  "KEY PROJECT: THE DETECTION AND MONITORING OF ELECTROMAGNETIC COUNTERPARTS OF GRAVITATIONAL WAVE SOURCES WITH SWIFT IN O3"

We seek to identify and follow-up EM counterparts of GW triggers detected by ALIGO and AVirgo. To identify EM counterparts, Swift will perform a large scale shallow tiling, covering the highest probability regions from which the GW trigger is likely to have originated. These are selected by convolving the GW error regions with galaxy catalogs. Based on lessons learned during O2, including the detection of the first NS-NS merger event with an EM counterpart, GW 170817, and through collaboration with Fermi/GBM, we seek to improve this follow-up, maximizing the science return. In addition we request deep follow-up observations at high priority in order to detect and characterize any EM counterpart detected either by Swift or other observatories, in X-ray or optical/UV.

"TESTING A NEW MODEL FOR GRB PROMPT EMISSION FROM OPTICAL TO GAMMA-RAYS AND EXPLORING GRBS AS STANDARD CANDLES"

The cosmological origin of Gamma Ray Bursts (GRBs) combined with their brightness in the gamma-ray regime lead to great expectations in using these sources as cosmological probes. In addition, the recent discovery of gravitational waves from black hole binary mergers marks the advent of a brand new field in astronomy in which GRBs will definitely play a major role. However, before using GRBs as tools we must first understand the origin and nature of the radiations released during these powerful explosions and investigate if GRBs can be established as standard candles. The aim of our project is to (i) probe the nature of GRB prompt emission from optical to the gamma-rays, (ii) explore the transition between prompt and afterglow emissions, and (iii) explore GRBs as standard candles.

"CHASING OBSCURING WINDS WITH SWIFT"

Obscuring winds are remarkably different from the commonly seen warm-absorber winds in AGN. They exhibit large columns of high-velocity gas close to the black hole. They produce broad UV absorption lines and shield much of the X-ray radiation. This has important implications for the launching mechanism of AGN outflows. These recent extraordinary findings were made possible by Swift monitoring of the X-ray hardness variability, and subsequent joint observations with XMM-Newton, NuSTAR, and HST. We propose to extend our Swift monitoring of a sample of seven suitable AGN to broaden our understanding of this phenomenon. We request weekly Swift monitoring of them in order to trigger joint XMM-Newton/NuSTAR/HST ToO observations (proposed separately). In total 98 ks of Swift time is requested.

"PROBING THE ERUPTION STATISTICS AND EVOLUTION OF THE UNIQUE RECURRENT NOVA M31N 2008-12A"

M31N 2008-12a is a recurrent nova in M31 with a unique record of 9 observed eruptions in 9 years. Its ultra-short recurrence period presents the only opportunity to study a statistically significant number of eruptions from the same system. We propose a tailored 84-ks Swift X-ray/UV observing campaign of the predicted 2018 eruption as an integral part of a long-term project. The recent 2016 eruption deviated clearly from the previous pattern, underlining the importance of obtaining multi-eruption statistics. This benchmark data set will provide unparalleled insights into binary evolution and the eruption physics that determine the observable parameters. M31N 2008-12a remains the prime candidate for the progenitor of a type Ia supernova or an accretion induced collapse to a neutron star.

"UNIQUE INSIGHTS INTO SWIFT GRBS WITH THE VLA AND ALMA"

Radio observations of GRB afterglows with the VLA and ALMA can address several fundamental open questions in GRB science: (1) the composition of the relativistic ejecta through observations of the reverse shock radio emission, (2) the explosion properties of short GRBs, with implications for radio counterparts of Advanced LIGO sources, and (3) whether high-redshift GRBs form a distinct population that may point to Pop III massive star progenitors. Here we propose to address these questions using on-going JVLA and new ALMA programs, which represent the most comprehensive radio/millimeter view of Swift GRBs. The proposal takes advantage of the unparalleled sensitivity of VLA and ALMA, and builds on our long-term success in radio studies of GRBs.

"THE NATURE AND ACCRETION FLOW PROPERTIES OF SUB-LUMINOUS X-RAY BINARIES"

Very-faint X-ray transients undergo outbursts of accretion with a peak X-ray luminosity much lower than that of other black hole and neutron star low-mass X-ray binaries. Studying these objects is of great interest because they trace a poorly understood accretion regime and may represent a missing population of short-period binaries or neutron stars with relatively strong magnetic fields. To study the outburst of a very-faint X-ray transient in detail, we propose 30 ks of Swift ToO monitoring observations (30x1 ks every other day), and 8 hr of deep VLA radio observations (2x4 hr). Complemented by guaranteed-time optical and near-infrared monitoring with Faulkes and SMARTS, these data allow us to investigate the nature of the binary and the properties of the accretion in/out flow.

"TOWARDS THE FULL IDENTIFICATION OF THE 3FHL CATALOG"

We propose to use Swift to search for X-ray and optical/UV counterparts of the 20 brightest unassociated objects in the 3FHL catalog. This catalog of sources detected by Fermi/LAT above 10 GeV is the deepest look at the very high-energy sky and will be used by CTA to plan most of the observations. Making it as complete as possible will result in stronger detections and characterizations of the EBL, better understanding of the origin of the IceCube neutrino flux and better planning for CTA. These observations will be coupled to our ongoing optical spectroscopic and photometric campaigns to measure the redshift of the proposed objects rendering this program highly efficient.

"ROTATION AND CHEMICAL HETEROGENEITY OF HYPERACTIVE COMET 46P/WIRTANEN"

We propose to use Swift-UVOT to measure rotational variations of the gas and dust surrounding comet 46P/Wirtanen. We will derive the rotational period of the nucleus from continuum observations and will look for evidence of rotational chemical variability in the production rates of OH, CN, C2, and other volatiles. We will compare the rotation and chemical variability before and after the comet s approach to the Sun to measure changes in the rotation period caused by gas jets. This allows us to evaluate the chemical heterogeneity of the nucleus, and how comets evolve through their activity. The Swift observations will provide critical context to the anticipated world-wide observing campaign of this close-approach comet.

"TESTING THE ORIGIN OF PERIODIC VARIABILITY FOR THE BINARY CANDIDATE QUASAR PG1302-102"

The quasar PG1302-102 exhibits periodic optical variability and was identified as a sub-pc supermassive black hole binary (SMBHB) candidate. If PG1302 consists of an unequal-mass SMBHB, the relativistic motion of the secondary BH will produce strong Doppler modulations, even if the rest-frame luminosity is constant. This effect can explain the variability in optical, UV and X-rays (including our observations from Cycle 13). However, the UV/X-ray light curves are sparse and, given the 5yr period of PG1302, additional observations are needed. We propose to continue multi-wavelength monitoring of PG1302 with UVOT and XRT to robustly test the relativistic boost hypothesis. Swift is uniquely suited to perform this test, as it can cover the optical, UV and X-ray bands simultaneously

"GROUND-BASED OPTICAL STUDIES OF SWIFT GAMMA-RAY BURSTS, CYCLE 14"

We will continue to conduct optical photometry of Swift GRBs with the Lick 0.76-m Katzman Automatic Imaging Telescope (KAIT) to complement the optical studies to be done with Swift (e.g., during times when the object is not available to Swift, or more quickly and with higher cadence than Swift). Optical photometry with the Lick Nickel 1-m telescope will be obtained as the afterglow fades beyond KAIT’s capabilities. We will also obtain temporal series of optical spectra, as well as deep photometry, with the Lick 3-m and the Keck 10-m telescopes. One goal of the spectra is to search for evidence of a supernova contribution. If circumstances permit, will also conduct Lick/Keck spectropolarimetry of the GRB optical afterglow and/or the supernova component, to search for asymmetries.

"PROBING A SCENARIO OF MULTIPLE RECOLLIMATION SHOCKS IN THE BL LAC MRK 421"

The origin and location of the non-thermal particle acceleration zone in active galactic nuclei (AGN) jets is one of the major questions still pending for these objects. The current consensus scenario involves a first-order Fermi process of a highly relativistic flow passing through a strong shock close to or in the radio core, revealed by very long baseline interferometry (VLBI). The common observations of multiple VLBI stationary knots in high-frequency-peaked BL Lacs (HBLs) can be interpreted as multiple recollimation shocks accelerating particles along jets. Hence, a unique pattern of the variability should appear after each strong flare, particularly well adapted for the X-ray bright BL Lac Mrk 421 and the capabilities of the Swift instruments.

"SEEKING THE SOURCES OF THE HIGHEST-ENERGY COSMIC NEUTRINOS WITH SWIFT"

We propose further prompt searches for X-ray and UV/optical counterparts to IceCube high-energy (E>~30 TeV) likely-cosmic neutrinos with Swift. Using realtime high-energy event reconstruction algorithms running at the South Pole, we will set the selection criteria such that we will trigger four neutrinos per year. Three proposed triggers will prompt a 7-pointing mosaic by Swift, providing >50% coverage of the neutrino localization to 1 ks depth in <10 hours, while one single proposed trigger will prompt a 19-pointing mosaic providing ~50% coverage to 1 ks depth in <16 hours. Discovery of even a single electromagnetic counterpart to a high-energy neutrino would revolutionize our understanding of the source population and potentially reveal the origins of the highest-energy cosmic rays.

"TESTING THE ULX UNIFIED MODEL WITH SWIFT MONITORING OF NGC 6946 X-1"

In recent years, a unified picture of Ultraluminous X-ray sources has been derived from its spectral properties. In this model, the hardest, most luminous ULXs are observed face-on, revealing the hottest part of the super-Eddington accretion flow, while softer, less-luminous ULXs that show evidence for Ultrafast Outflows are observed at larger inclinations. If this unification model is correct, it should have observable implications on the long term variability of ULXs, as the edge-on systems should show more variability due to clumpy material along the line of sight. In this proposal, we aim to test this model by monitoring the well-known ULX NGC 6946 X-1, which, according to the unified picture is viewed at higher inclinations. NGC 6946 X-1 is an ideal target because, while little is kno

"COMPLETE PERIASTRON COVERAGE OF THE 50-YEAR BINARY PSR J2032+4127/ MT91~213."

In 2015, the gamma-ray and radio pulsar PSR~J2032+4127 was identified as the compact object in a binary system, together with the Be star MT91 213. The source holds particular interest, as its location coincides with a steady, extended TeV gamma-ray source, TeV J2032+4130. The binary orbit is highly eccentric, with a period of 45-50 years and periastron predicted for November 2017. We have been monitoring the system with Swift throughout Cycle 13, over which time the source X-ray flux has increased dramatically. We have established a multi-instrument observing campaign to cover the periastron period. Here we propose continued X-ray monitoring with Swift through Cycle 14. This will allow stringent tests of models for the geometry and high-energy emission mechanisms in this system.

"PROBING THE MASS LOSS OF THE HOTTEST GAS PLANETS"

Close-in giant gas planets experience a continuous, photoevaporative mass loss that can erode their gaseous envelopes. This mass loss has been observed only in a few systems and we propose the first systematic study in the NUV using Swift/UVOT. We proved that UVOT enables NUV photometry better than 0.5%, sufficient for our science goals. Furthermore, our Swift pilot study of WASP-121 showed excess NUV absorption by a thick, escaping planetary atmosphere as predicted by our simulations; a feature previously only known for WASP-12 b and HD 209458b. We now propose to measure the NUV transit depth of six carefully selected hot gas giant planets to measure their NUV transit depth. This allows us to test models, which make clear predictions for the NUV absorption depending on irradiation level.

"ROBOTIC SPECTROSCOPIC FOLLOWUP OF SWIFT GRBS"

We propose rapid and robotic multicolor imaging and spectroscopy of GRB afterglows on the Palomar 60-inch telescope. Robotic spectroscopy is available on the fully proven Spectral Energy Distribution Machine (a low resolution integral field spectrograph). Our annual yield is expected to be ten multi-band photometric observations and five redshifts. We will disseminate these findings quickly and thereby enable wider follow up of SWIFT bursts. The goals of our group are are: (i) provide automated, rapid spectroscopy enabling immediate redshift measurement and sensitive constraints on the color evolution of GRBs; (ii) rapidly identify high-redshift and dust-obscured GRBs; (iii) identify reverse shocks and constrain energetics of GRBs; (iv) collect unbiased samples for demographic study.

"DETAILED MAPPING OF EXTREME MASS-LOSS FROM EVOLVED MASSIVE STARS WITH SWIFT"

Contrary to expectations from current stellar evolutionary models, recent observations uncovered the ejection of shells of material by massive stars in the years before the supernova explosion, thus revealing our inadequate understanding of the last stages of evolution of massive stars. Here we propose a focused Swift project, with the aim to (i) constrain the mass-loss history of massive stars before explosion, employing multi-wavelength observations of the supernova shock breaking out through a dense medium; and (ii) constrain the efficiency of cosmic-ray acceleration by supernova shocks. This study will open up a new window of investigation on the SN shock circum stellar medium interaction.

"ACCRETION DISK REVERBERATION MAPPING OF A SUPER-EDDINGTON AGN"

At high mass accretion rates, accretion disks are expected to be significantly different from the standard optically thick, geometrically thin disk. However, observational tests of disk structure are rare. Emission line reverberation mapping has revealed that the broad line region in super-Eddington AGN are quite different, but what about the disk? The accretion disk reverberation mapping technique provides a way to observationally test the structure of the accretion disk at high accretion rates. Through flexible and high-cadence monitoring, Swift has revolutionized accretion disk reverberation over the last few years. Here, we propose to apply this technique to a super-Eddington AGN for the first time, to explore the structure of disks at extreme mass accretion rates.

"REVEALING THE TRANSIENT X-RAY BINARY POPULATION OF THE LMC"

We propose systematic monitoring observations of 25 fields in the Large Magellanic Cloud (LMC) with quasi-bi-weekly cadence. This will be the first dedicated X-ray monitoring campaign of a large area of the LMC. With these observations we will: (a) identify the elusive, transient High-Mass X-ray binary (HMXB) populations in the LMC; (b) obtain a more complete census of its HMXB populations that will allow us to better constrain their formation efficiency; (c) constrain their orbital periods; (d) identify new accreting pulsars. Through this campaign we will study the populations of HMXBs in a galaxy with a metallicity bridging the gap between the SMC and our Galaxy, allowing us to constrain models for their formation and evolution.

"XRT AND UVOT MONITORING OF THE TIDAL DISRUPTION FLARE ASASSN-14LI TO DETECT THE NEWLY FORMED ACCRETION DISK"

We propose high-cadence XRT and UVOT monitoring observations (2ksx8 visits per day for 3 days) of Rosetta Stone tidal disruption flare (TDF) ASASSN-14li at late times. Our main goals are (1) search for a correlation between the X-ray and UV light curves, and (2) detect an X-ray-UV time lag/lead in the range of a few hours to tens of hours. Any detected lag will not only establish unambiguously the presence of an accretion disk in a TDF for the first time, but will also directly give us the minimum size of the putative disk. ASASSN-14li is currently the only TDF where such measurements can be made. Swift, with its excellent X-ray sensitivity and UV capability, combined with fast maneuvering ability, is currently the only observatory that can perform simultaneous X-ray and UV observations.

"TOO MONITORING OF THE RE-AWAKENING AGN IN MRK590: CATCHING THE MONSTER IN THEACT!"

After a 10-year hiatus, Mrk590 appears to be rekindling its nuclear activity! Existing Swift data strongly suggest that the AGN is likely to turn on again in the near future. We wish to seize this rare and fortuitous opportunity to document, for the first time ever, the onset of AGN activity since this can lead to significant insight on the long-standing issue of how AGNs are fueled. Once triggered by another program (PI:Vestergaard) we ask to first observe Mrk590 ~daily with Swift for up to 60 days and then for 5 ~bi-weekly follow-up observations to establish if Mrk590 has entered a stable high or low flux state. We also ask for two 20ks NuSTAR observations to place tighter constraints on the potential emergence of a weak soft X-ray component and perhaps a high-energy reflection component

"MONITORING THE SLEEPING MONSTER IN AGN MRK590 AND CLUES TO THE NATURE OF ITS RADIO EMISSION"

After a 10-year hiatus, Mrk590 appears to be rekindling its nuclear activity! Existing Swift data strongly suggest that the AGN is likely to turn on again in the near future. We wish to seize this rare and fortuitous opportunity to document, for the first time ever, the onset of AGN activity as it occurs since this can lead to significant insight on the long-standing problem of how AGNs are fuelled. We propose to monitor Mrk590 with Swift (biweekly) and with the VLBA (~bi-monthly). We aim to determine the nature of the radio emission, confirm its connection to the X-ray processes, and to record the potential black hole state changes from low/hard to high/soft states that have not yet been observed for massive black holes. This program is a trigger for another program (PI: Vestergaard).

"SWIFT MONITORING OF NEUTRON STAR POWERED ULTRA-LUMINOUS X-RAY SOURCES"

Following a series of remarkable recent discoveries, we now know that some of the most luminous members of the ultraluminous X-ray source (ULX) population are actually powered by highly super-Eddington neutron star accretors. Three such systems are known: M82 X-2, NGC 7793 P13, and NGC 5907 ULX1. Here we propose to extend our successful Swift monitoring program performed in the last AOs of the latter two of these systems. NGC 7793 P13 and NGC 5907 ULX1 are sufficiently isolated for Swift to provide robust fluxes, across the full visibility window available for each source in the upcoming cycle. These observations will help to reveal the nature and physical properties of the most extreme accretors known.

"MODELING THE PHYSICAL PARAMETERS AND ULTRAVIOLET DUST EXTINCTION CURVE IN FIVE NEARBY DWARF GALAXIES"

We propose to use Swift/UVOT to observe five recently-discovered dwarf galaxies in the Local Volume. We will combine new observations in the UV filters with archival optical imaging to model the spectral energy distributions (SEDs) of each tiny galaxy, revealing information including the shape of the dust extinction curve, stellar masses, and star formation history. This information will contribute to our understanding of the formation and evolution of dwarf galaxies, which in turn will inform theories for the growth of structure at small scales.

"A RARE LOOK AT A BLACK HOLE TRANSIENT EMERGING FROM QUIESCENCE"

Given the limited sensitivity of all-sky-monitors and the unpredictability of black hole transients, the early phases of their outbursts are typically not well covered. We propose a brief and well-timed Swift monitoring campaign to catch the rise of the next outburst of the black hole transient H1743-322. The regularity of its outbursts (once every ~245-270 days) provides us with a rare opportunity to follow a transient as it emerges from quiescence. Our X-ray observations will complement near-IR monitoring and we request additional VLA observations during the outburst rise. The goals of this campaign are to provide input to outburst disk-instability models and to study disk-jet coupling during outburst rise. We request a maximum of 43 (1 ks) Swift observations and 5 hrs of VLA time.

"THE LEGACY OF SWIFT-BAT: THE TALE OF AGN AT HARD X-RAYS"

We propose a quick snapshot program with Swift to observe the remaining 29 AGN detected in the 100 month BAT survey that do not have any X-ray observation in the 0.5-10 keV band. These AGN are expected to be mostly absorbed by LogNH<23 and as such are the perfect targets for a 5ks observation (each) with Swift. This will render complete the 100m high-latitude BAT survey, providing a heritage-quality sample that we will use to: 1) address the space density of Compton-thick AGN, 2) verify whether absorbed AGN are intrinsically less luminous than unabsorbed one, and 3) study the evolution of the most powerful blazars.
