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).
- NuSTAR Guest Observer AO1 Deadlines Are Near (29 Oct 2014)
The deadline for requesting project assistance for proposed
NuSTAR pointings which have been flagged as having
contaminated stray light is November 11th and the
deadline for proposal submission is November 25th .
- Chandra Observatory Identifies Impact of Cosmic Chaos on Star Birth (28 Oct 2014)
et al. (2014, Nature, in press)
have analyzed the Chandra data for the nearby cool-core clusters of galaxies
Persesu and Virgo and conclude that turbulence may be preventing hot gas there
from cooling, addressing a long-standing question of why galaxy clusters do
not form large numbers of stars.
- INTEGRAL IBIS AGN Catalog (24 Oct 2014)
This catalog of the classification and X-ray properties of 272
active galactic nuclei which have been detected by the INTEGRAL IBIS instrument
et al. 2012, MNRAS, 476, 1750) is now available in Browse
- 5th NuSTAR Public Data Release (23 Oct 2014)
214 new NuSTAR data sets from the first 24 months of observations
were released to the public NuSTAR archive on September 23rd. NuSTAR data are
accessible via the usual HEASARC archive interfaces, i.e.,
by querying the NuSTAR master table (numaster). NuSTAR data can also be
accessed from the HEASARC FTP site.
- Browse bug fix (22 Oct 2014)
Bug fix to Browse v. 8.4. Fixed calculation of data product download size for the Create Download Script option. ...
- Fermi Finds Hints of Starquakes in Magnetar Burst 'Storm' (22 Oct 2014)
Fermi detected a rapid-fire "storm"
of high-energy blasts from the highly magnetized neutron star (magnetar)
SGR J1550-5418 on Jan. 22, 2009. Now Huppenkothen
et al. 2014, ApJ, 787, 128 have discovered underlying
signals related to seismic waves rippling throughout the magnetar.
Such signals were first identified during the fadeout of rare giant flares
produced by magnetars.
