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 not only data
obtained by high-energy astronomy missions observing in the
extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, but also data from
space missions, balloons, and ground-based facilities that have studied the
relic cosmic microwave background (CMB).

- Swift X-Ray Telescope Cluster Survey (SWXCS) Catalog (27 Mar 2015)
This catalog of 263 X-ray group and cluster candidates detected
by the Swift XRT in ~ 3,000 high Galactic latitude fields in the period from
2005 to 2012 (from Liu
et al. 2015, ApJS, 216, 28) is now available in Browse and
Xamin, along with the
catalog of 383 possible optical, other X-ray and/or S-Z
counterparts of these sources which was presented in the same paper.
- Hubble, Chandra Find Clues that May Help Identify Dark Matter (27 Mar 2015)
Using observations from the Hubble Space Telescope and Chandra
X-ray Observatory, astronomers have found that dark matter does not slow down
when colliding with itself, meaning it interacts with itself less than
previously thought. Harvey et al. (2015,
Science, 347, 1462) argue that this finding narrows down
the options for what this mysterious substance might be.
- Proceedings of the 10th INTEGRAL Workshop Available Online (26 Mar 2015)
The Proceedings of the 10th INTEGRAL Workshop: A Synergistic View of the High-Energy Sky held
15-19 September 2014 in Annapolis, MD is now available online via Proceedings of Science.
- Suzaku, Herschel Link a Black-hole 'Wind' to a Galactic Gush of Star-forming Gas (26 Mar 2015)
By combining observations in X-rays by Suzaku with infrared
observations by Herschel, Tombesi
et al. (2015, Nature, 519, 436) have connected a fierce
"wind" produced near the monster black hole in the galaxy IRAS F11119+3257 to
an outward torrent of cold gas a thousand light-years across. The finding
validates a long-suspected feedback mechanism enabling a supermassive black
hole to influence the evolution of its host galaxy.
