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).
- Chandra Weighs Most Massive Galaxy Cluster in Distant Universe (22 Dec 2014)
A newly discovered galaxy cluster, XDCP J0044.0-2033 nicknamed
the Gioiello or Jewel Cluster, is the
most massive cluster ever detected with an age of 800 million years or less.
Using data from Chandra, Tozzi et al. (2015, ApJ, in
press) have accurately determined the mass and other
properties of this cluster, an important step in understanding how
galaxy clusters have evolved over cosmic time.
- Chandra Cycle 17 Call for Proposals Has Been Released (18 Dec 2014)
The Chandra X-ray Center is pleased to announce the release of the
Chandra Cycle 17 Call for Proposals (CfP). The CfP, the Proposers' Observatory
Guide (POG), proposal planning software, and general information are posted
on the above web site. The deadline for Cycle 17 proposals to be
submitted by is 2015 March 17, 6:00pm EDT.
- New Swift Gamma-Ray Burst Catalog Web Site (17 Dec 2014)
This web site includes search tools to query the Swiftgrb
database at the HEASARC and external sites for additional information on the
GRBs. The Swiftgrb database contains information for each burst detected by
as well as data products obtained from all instruments on Swift (currently
through Dec 2012).
- Chandra CALDB 4.6.5 installed at the HEASARC (16 Dec 2014)
CalDB 4.6.5 is now installed and available at the HEASARC. Chandra 4.6.5 was released on December 16, 2014. Note that this release requires CIAO 4.3 or higher...
- WISE Blazar-like Radio-Loud Source (WIBRaLS) Catalog (16 Dec 2014)
This catalog of 7,855 sources classified as BL Lacs, FSRQs, or
mixed candidate blazars based on their WISE mid-IR colors being similar to those
of confirmed gamma-ray blazars (from D'Abrusco et al. 2014, ApJS, 215, 14)
is now available in Browse and Xamin.
- XSPEC 12.8.2g Released (15 Dec 2014)
