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.
The HEASARC is a member of the NASA Astronomical
Virtual Observatories (NAVO) where we work with other NASA archives to
ensure comprehensive and consistent VO access to NASA mission datasets.
Users may now query the HEASARC's catalogs using VO-enabled services and
specialized tools. This page describes
how to get to the HEASARC VO-enabled
services and provides information on other HEASARC VO activities.

- COSMOS Field X-Ray & Far-IR Detected AGN Multiwavelength Properties Catalog (25 Jul 2017)
The catalog of the multiwavelength properties of 692 X-ray
detected AGN and their far-infrared (FIR) detected host galaxies in the
redshift range from 0.1 to 4 that have been found in the COSMOS field (from
Lanzuisi

- SkyView v3.3.0: Swift XRT surveys (24 Jul 2017)
Versions 3.3.0 of SkyView was released today. This includes an all-sky mosaic of the Swift XRT observations. Over 129,000 XRT observations were combined to give coverage of just under 6% of the sky. A set of three surveys were produced: … Continue reading →
- Chandra CALDB 4.7.5.1 installed at the HEASARC (21 Jul 2017)
CalDB 4.7.5.1 is now installed and available at the HEASARC. Chandra 4.7.5.1 was released by the CXC on July 20, 2017...
- NuSTAR CALDB Update (21 Jul 2017)
The NuSTAR CALibration DataBase was updated on July 21, 2017 (CALDB version 20170720). This updates the NuSTAR clock correction file to version 73, valid through 2017-07-20.
- Press Release: Astrosat, Chandra, Hubble Simultaneously Detect a Coronal Explosion on the Nearest Planet-Hosting Star (20 Jul 2017)
Stars like Proxima Centauri are known to flare on timescales of a
few minutes to hours. The ongoing analysis of the data for this flare detected
on 31 May 2017 suggests
that the flux increases by several orders of magnitude in both X-rays and UV
and lasts ~1800 seconds. The energy released during this flare is of the order
of ~10 30 erg, 100 times the energy of large solar
flares.
- Sloan Digital Sky Survey Quasar Catalog (12th Data Release: DR12Q) (20 July 2017)
The SDSS DR12Q Catalog listing the X-ray, UV,
optical, IR and radio properties of 297,301 quasars, as well as their
redshifts, that were identified in the Baryon Oscillation Spectroscopic Survey
(BOSS) of the SDSS-III via visual inspection of their spectra (from Paris
et al. 2017, A&A, 597, A79) is now available in
Browse and
