    Latest News

  • NASA Missions Harvest a 'Passel of Pumpkin' Stars (28 Oct 2016)
    Steven Howell and colleagues (2016, ApJ, 831, 27) using observations from NASA's Kepler and Swift missions have discovered a batch of rapidly spinning stars that produce X-rays at more than 100 times the peak levels ever seen from the sun. The stars, which spin so fast they've been squashed into pumpkin-like shapes, are thought to be the result of close binary systems where two sun-like stars merge.
  • IC 1805 Young Massive Cluster XMM-Newton Source Catalog (28 Oct 2016)
    A catalog of 191 X-ray sources found in a 49-ks XMM-Newton EPIC observation of the IC 1805 open cluster (from Rauw & Nazé 2016, A&A, 594, A82) is now available in Browse and Xamin.
  • NuSTAR CALDB Update (25 Oct 2016)
    The NuSTAR CALibration DataBase was updated on October 25, 2016 (CALDB version 20161021). This updates the NuSTAR clock correction file to version 63, valid through 2016-10-21.
  • Fermi Finds Record-breaking Binary in Galaxy Next Door (13 Oct 2016)
    Using data from NASA's Fermi Gamma-ray Space Telescope and other facilities, an international team of scientists has found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed LMC P3, contains a massive star and a crushed stellar core that interact to produce a cyclic flood of gamma rays, the highest-energy form of light. A paper on these results has just appeared in ApJ and is available online here.
  • XSPEC 12.9.0q,r,s Released (4 Oct 2016)
    XSPEC patches 12.9.0q,r,s, released August 19. Fixes issues with simftest, the GW method for MCMC, and 2-D contour plotting.
  • Viewing tool updated (28 Sep 2016)
    Support for NICER has been added, and support for Hitomi has been removed.
