  • Fermi LAT High-Energy (1FHL) Source Catalog (17 Apr 2015)
    This catalog of 514 gamma-ray sources detected at energies above 10 GeV by the Fermi Large Area Telescope in its first 3 years of operations (taken from Ackermann et al. 2013, ApJS, 209, 34) is now available in Browse and Xamin.
  • Swift Data Reprocessing (17 Apr 2015)
    The Swift Data Center is now reprocessing the Swift data for the entire mission in chronological order using the current version of the Swift Data Center pipeline (v. 3.16.08). All the data for 2005 have been reprocessed and delivered to the HEASARC. The archives in Italy and UK are currently populating their archives with the new data. Currently the reprocessing rate is about 3 months per month.
  • Astronomers discover two classes of Type Ia Supernovae (14 Apr 2015)
    Milne et al. 2015, ApJ, 803, 20 have found that type Ia supernovae commonly used to measure distances in the universe fall into distinct populations not recognized before. The data collected with Swift were crucial because the differences between the populations are subtle in visible light, but became obvious only through Swift's dedicated follow-up observations in the ultraviolet with UVOT.
  • XSPEC 12.8.2n Released (13 Apr 2015)
    Updated April 8, 2015. Corrections for the feld abundance table values for the elements Cl, Cr, Mn, and Co.
  • XSPEC 12.8.2m Released (02 Apr 2015)
    Updated April 2, 2015. Fixes an error in the Goodman-Weare option for MCMC which caused confidence regions to be about 70% of their correct size, and performance improvements.
  • Updated IRAM Plateau de Bure Interferometer Observation Log (02 Apr 2015)
    The latest version of the IRAM PdBI observing log (Dan et al. 1991-2015, IRAM Newsletters) containing 18,443 observations completed through September 30, 2013 is now available in Browse and Xamin.
