  • 2XMMi/SDSS Galaxy Cluster Survey (21 Jul 2014)
    This catalog listing the X-ray and optical properties of 145 X-ray-detected clusters of galaxies (Takey et al. 2014, A&A, 564, A54) is now available in Browse and Xamin.
  • Chandra Cycle 16 Accepted Proposals and Targets Lists Are Now Available (17 Jul 2014)
    The peer-review recommended targets and proposals for Chandra Cycle 16 for regular, large, multicycle and XVP-type programs, as well as the approved joint proposals with other ground-based and/or satellite facilities, theory proposals and archive proposals, have been released.
  • Low-Frequency Radio Catalog of Flat-Spectrum Sources (LORCAT) (16 Jul 2014)
    This catalog of 28,358 radio sources with flat spectra between 325/352 MHz and 1400 MHz (from Massaro et al. 2014, ApJS, 213, 3) is now available in Browse and Xamin.
  • BeppoSAX High-Energy Large Area Survey (HELLAS) X-Ray Source Catalog (15 Jul 2014)
    This catalog of 147 5-10 keV X-ray sources detected by the BeppoSAX MECS in a survey of 85 sq.deg. (from Fiore et al. 2001, MNRAS, 327, 771) is now available in Browse and Xamin. The related table of radio sources and/or upper limits at the positions of these X-ray sources (from Ciliegi et al. 2003, MNRAS, 342, 575) is also available
  • Chandra CALDB 4.6.2 installed at the HEASARC (14 Jul 2014)
    CalDB 4.6.2 is now installed and available at the HEASARC. Chandra 4.6.2 was released on July 9, 2014. This release corrects an error in the HRC branch index file which causes the 2012 and 2013 HRC-I BKGRND files to be selected in reversed order, which affects HRC-I-related tools such as hrc_bkgrnd_lookup and fluximage. Note that this release requires CIAO 4.3 or higher...
  • Out of An Hours-long Explosion, A Stand-In For The First Stars (11 Jul 2014)
    Astronomers analyzing a long-lasting blast of high-energy light observed in 2013 report finding features strikingly similar to those expected from an explosion from the universe's earliest stars. If this interpretation is correct, the outburst validates ideas about a recently identified class of gamma-ray burst and serves as a stand-in for what future observatories may see as the last acts of the first stars.
