Swift takes aim at the first gravitational wave transient GW150914

On 2015 September 14 the Advanced LIGO experiment detected with high significance its first signal of gravitational waves (GWs). The event, dubbed GW150914, lasted only 0.2 s and was likely produced by the merger of two heavy black holes, about 30 times the mass of the Sun. Despite the event's poor localization (~590 square degrees), a large number of space-based and ground-based observatories pointed at that region of the sky in order to detect the electromagnetic signal emitted by the GW source. Swift observations were focused on nearby galaxies within the GW error region. No new sources were found in the 4.7 square degrees that were covered. A paper describing the results of the Swift campaign is now accepted for publication on MNRAS Letters.

NASA's Swift Spots its Thousandth Gamma-ray Burst

NASA's Swift spacecraft has detected its 1,000th gamma-ray burst (GRB). GRBs are the most powerful explosions in the universe, typically associated with the collapse of a massive star and the birth of a black hole.

Swift Cycle 12 GI Program

NASA received 185 proposals, requesting a total observing time of 15.8 Ms and $6.0M in funds for 1,555 targets. Considering PIs and Co-Is, more than 600 individual scientists responded to the Swift Cycle 12 call. The Swift Cycle 12 Peer Review will be held in December to evaluate the merits of submitted proposals. Results will be posted in late December 2015.
