The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for NASA's (and other space agencies') missions studying electromagnetic radiation from extremely energetic cosmic phenomena ranging from black holes to the Big Bang. Since its merger with the Legacy Archive for Microwave Background Data Analysis (LAMBDA) in 2008, the HEASARC archive contains data obtained by high-energy astronomy missions observing in the extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from space missions, balloons, and ground-based facilities that have studied the relic cosmic microwave background (CMB) radiation in the sub-mm, mm and cm bands.

Try ROSAT 3c273 1d to get ROSAT data within one degree of 3C273 or chanmaster bii>80 status='archived' to get archived Chandra observation data near the north galactic pole.

Note: For more than one target or when using any qualifier other than a mission, use quotes around targets that have embedded white space.(e.g., 'ar lac').

Latest News
  • Murchison Widefield Array Low-Frequency Radio Survey of the Kepler K2 Field 1 (09 Dec 2016)
    A catalog of 2,556 154- and 185-MHz radio sources found in an observation by the MWA that was contemporaneous with the Kepler K2 Field 1 pointing, covering the North Galactic Cap, (from Tingay et al. 2015, AJ, 152, 82) is now available in Browse and Xamin.
  • NuSTAR CALDB Update (08 Dec 2016)
    The NuSTAR CALibration DataBase was updated on December 8, 2016 (CALDB version 20161207). This updates the NuSTAR clock correction file to version 66, valid through 2016-12-07. This version is the long-awaited "corrected" clock correction file that tracks clock drift by fitting to screened clock data.
  • Two-Year Extension for ESA-led Missions (7 Dec 2016)
    ESA's Science Programme Committee (SPC) has confirmed two-year extensions for nine scientific missions including INTEGRAL and XMM-Newton. This secures their operation until the end of 2018.
  • XMM-Newton AO-16 Results Released (02 Dec 2016)
    The list of XMM-Newton observing proposals accepted by the AO-16 Observing Time Allocation Committee is now available.
  • INTEGRAL IBIS 11-Year Hard X-Ray Survey Above 100 keV Source Catalog (29 Nov 2016)
    The all-sky catalog of 132 transient and persistent sources detected above 100 keV by INTEGRAL IBIS during 11 years of operations (INTEGRAL revolutions 26 to 1377) published in Krivonos et al. (2015, MNRAS, 448, 3766) is now available in Browse and Xamin.
  • Long-sought Signal Deepens Mystery of Fast Radio Bursts (FRBs) (21 Nov 2016)
    What causes split-second blasts of radio waves that appear in the sky from billions of light years away is one of the most perplexing mysteries in astronomy. Now, for the first time, astronomers using the Swift BAT have seen a flash of high-energy gamma-rays that looks as if it was emitted by the same event that produced an FRB on November 4, 2013. A paper by DeLaunay et al. on this event has just appeared in ApJ and is available online here .
