    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. The results of the Peer Review will be posted in late December 2015.
  • Astrosat, India's First Astronomy Satellite Launched into Space (28 Sep 2015)

  • Sgr A*, Milky Way's Super-Massive Black Hole, Shows Signs of Increased Chatter (28 Sep 2015)
    3 orbiting X-ray space telescopes (Swift, Chandra and XMM-Newton) have detected an increased rate of X-ray flaring from Sgr A*, the usually quiet giant black hole at the center of our galaxy, in the last year compared to the previous 14 years of long-term monitoring. In a recently accepted paper, Ponti et al. (2015, MNRAS, in press) discuss whether this is normal behavior that was unnoticed due to limited monitoring, or if these flares were triggered by the recent close passage of the mysterious, dusty object "G2".
