    Latest News

  • Viewing tool updated (14 Dec 2017)
    The Sun angle constraint for NuSTAR observations has been updated in the Viewing tool to be greater than 43 degrees. This reflects the change by the NuSTAR Science Operations Center to ensure stable pointing. This new, slightly more restrictive range applies to all future ToO requests and Cycle 4 proposals.
  • Hitomi CALDB Data Updated (14 Dec 2017)
    The Hitomi CALDB has been updated for the SGD (update version 20171207).
  • Hitomi Master Observations Table (07 Dec 2017)
    The table of all Hitomi observations that were completed during its period of operations is now available in Browse and Xamin.
  • The Amazing Year 2017 in High-Energy Astrophysics (07 Dec 2017)
    2017 was a banner year for our field. We list here some of the important events in high-energy astronomy (X-ray astronomy, gamma-ray astronomy, gravitational wave and cosmic-ray astronomy) which occurred and/or were announced in this last year. Let's see if 2018 can be even better!
  • Winners of the 2018 Breakthrough Prize in Fundmental Physics Have Been Announced (05 Dec 2017)
    Congratulations to Charles L. Bennett, Gary Hinshaw, Norman Jarosik, Lyman Page Jr., David N. Spergel, and the members of the WMAP Science Team for winning this prestigious award, the "Oscar of Science". The HEASARC is particularly happy since several current members of its LAMBDA component (Mike Greason, Nils Odegard and Janet Weiland) and its one-time director, Gary Hinshaw, were so honored.
  • NuSTAR CALDB Update (04 Dec 2017)
    The NuSTAR CALibration DataBase was updated on December 4, 2017 (CALDB version 20171204). This updates the NuSTAR clock correction file to version 76, valid through 2017-12-04.
