Latest News Lepine and Shara Northern Stars with Proper Motions > 0.15"/yr Catalog (19 Jun 2013) The LSPM-North catalog of 61,977 high-proper-motion stars (from Lépine & Shara 2005 AJ, 129, 1483) is now available in Browse and (within half a day) Xamin. INTEGRAL AO-11 General Program Approved (18 Jun 2013) The INTEGRAL AO-11 General Program, as recommended by the Time Allocation Committee (TAC) and approved on June 3 by the ESA Director of Science and Robotic Exploration (Prof. Alvaro Gimenez), has been released and the observers have been informed. The Turbulent, High-Energy Sky Is Keeping NuSTAR Busy (18 Jun 2013) NuSTAR keeps an eye on sudden changes in the high-energy sky Swift CALDB Updated (17 Jun 2013) The Swift Caldb has been updated for the SC (update version 20130606). Black Hole Naps Amidst Stellar Chaos (17 Jun 2013) NuSTAR teamed up with Chandra to show that the supermassive black hole in the Sculptor galaxy is no longer actively feeding. NASA News Feature: NASA-Led Study Explains Decades of Black Hole Observations (14 Jun 2013) A new study (Schnittman et al. (2013, ApJ, 769, 156)) confirms long-held suspicions about how stellar-mass black holes produce their highest-energy light. "Our work traces the complex motions, particle interactions and turbulent magnetic fields in billion-degree gas on the threshold of a black hole..." said lead researcher Jeremy Schnittman, an astrophysicist at NASA/GSFC. NASA News Feature: Astronomers Identify Dozens of Black Holes in M 31 Using Chandra Data (13 Jun 2013) Using data from the Chandra X-ray Observatory, researchers (Barnard et al. (2013, ApJ, 770, 148) have discovered an unprecedented bonanza of black holes in the Andromeda Galaxy, one of the nearest galaxies to the Milky Way. The 26 new black hole candidates belong to the stellar mass category, meaning they formed in the death throes of very massive stars and typically are 5 - 10 solar masses.
