  • Swift X-Ray Telescope Cluster Survey (SWXCS) Catalog (27 Mar 2015)
    This catalog of 263 X-ray group and cluster candidates detected by the Swift XRT in ~ 3,000 high Galactic latitude fields in the period from 2005 to 2012 (from Liu et al. 2015, ApJS, 216, 28) is now available in Browse and Xamin, along with the catalog of 383 possible optical, other X-ray and/or S-Z counterparts of these sources which was presented in the same paper.
  • Hubble, Chandra Find Clues that May Help Identify Dark Matter (27 Mar 2015)
    Using observations from the Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought. Harvey et al. (2015, Science, 347, 1462) argue that this finding narrows down the options for what this mysterious substance might be.
  • Proceedings of the 10th INTEGRAL Workshop Available Online (26 Mar 2015)
    The Proceedings of the 10th INTEGRAL Workshop: A Synergistic View of the High-Energy Sky held 15-19 September 2014 in Annapolis, MD is now available online via Proceedings of Science.
  • Suzaku, Herschel Link a Black-hole 'Wind' to a Galactic Gush of Star-forming Gas (26 Mar 2015)
    By combining observations in X-rays by Suzaku with infrared observations by Herschel, Tombesi et al. (2015, Nature, 519, 436) have connected a fierce "wind" produced near the monster black hole in the galaxy IRAS F11119+3257 to an outward torrent of cold gas a thousand light-years across. The finding validates a long-suspected feedback mechanism enabling a supermassive black hole to influence the evolution of its host galaxy.
  • South Polar Telescope Sunyaev-Zel'dovich (SPT-SZ) Survey Catalog (24 Mar 2015)
    This catalog of 677 galaxy cluster candidates detected at high (>= 4.5) significance in the 2500 square degree SPT-SZ survey (taken from Bleem et al. 2015, ApJS, 216, 27) is now available in Browse and Xamin.
  • Near-UV Detected Bright Early-M Dwarf Stars Catalog (23 Mar 2015)
    This catalog of ~800 nearby early-M dwarf stars with GALEX NUV fluxes signficantly in excess of their expected basal levels (taken from Ansdell et al. 2015, ApJ, 798, 41) is now available in Browse and Xamin.
