ROSES-24 Amendment 23: D.5 Swift General Investigator Amendment: IXPE Joint Observing Program and Change to NuSTAR Exclusive-Use Period

Jun 25, 2024

D.5 Neil Gehrels Swift Observatory General Investigator (GI) - Cycle 21 solicits proposals for basic research relevant to the Swift gamma-ray burst mission. The primary goal of this mission is to determine the origin of gamma-ray bursts (GRBs) and use these bursts to probe the early Universe. Two changes have been made to D.5 Swift GI: 1) A joint GI observing program with Imaging X-ray Polarimetry Explorer has been added and 2) all NuSTAR data acquired through the Swift GI Program will have a standard 6-month exclusive-use period, see Section 1.3.2. New text is in bold and deleted text is struck through. The proposal due date is unchanged: Phase-1 proposals are due by 4:30 p.m. Eastern time on September 26, 2024, via ARK/RPS.

On or about June 24, 2024, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2024" (NNH24ZDA001N) will be posted on the NASA research opportunity homepage and will appear on SARA's ROSES blog.

Programmatic information concerning D.5 Swift GI may be obtained from Mario Perez and Technical questions concerning this program element may be directed to Bindu Rani.

Astronomers See a Massive Black Hole Awaken in Real Time

In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, to track how the galaxy's brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy - likely the result of the sudden awakening of the massive black hole at its core.

NASA's Swift Learns a New Trick, Spots a Snacking Black Hole

Using NASA's Neil Gehrels Swift Observatory, which launched in 2004, scientists have discovered a black hole in a distant galaxy repeatedly nibbling on a Sun-like star. The object heralds a new era of Swift science made possible by a novel method for analyzing data from the satellite's X-ray Telescope (XRT).
