Try Xamin, the New HEASARC Discovery and Data Retrieval System
A faster, more powerful way to access data from the HEASARC
|
The High Energy Astrophysics Science Archive Research Center (HEASARC) is the
primary archive for NASA's (and other space agencies') missions dealing with
electromagnetic radiation from
extremely energetic 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's
holdings contain data
obtained by NASA's high-energy astronomy missions observing in the
extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as data from
missions, balloons, and ground-based facilities that have studied the relic
cosmic microwave background (CMB).

- Black Hole Naps Amidst Stellar Chaos (17 Jun 2013)
NuSTAR teamed up with Chandra to show that the supermassive black hole in the Sculptor galaxy is no longer actively feeding.
- NASA News Feature: NASA-Led Study Explains Decades of Black Hole
Observations (14 Jun 2013)
A new study (Schnittman
et al. (2013, ApJ, 769, 156)) confirms long-held suspicions
about how stellar-mass black holes produce their highest-energy light.
"Our work traces the complex motions, particle interactions and turbulent
magnetic fields in billion-degree gas on the threshold of a black hole..." said
lead researcher Jeremy Schnittman, an astrophysicist at NASA/GSFC.

Astronomers Identify Dozens of Black Holes in M 31 Using Chandra Data (13 Jun 2013)
Using data from the Chandra X-ray Observatory, researchers (Barnard
et al. (2013, ApJ, 770, 148) have
discovered an unprecedented bonanza of black holes in the Andromeda Galaxy,
one of the nearest galaxies to the Milky Way. The 26 new black hole candidates
belong to the stellar mass category, meaning they formed in the death throes
of very massive stars and typically are 5 - 10 solar masses.
- JPL Latest News: NuSTAR Finds Black Hole in NGC 253 "Napping" Amidst Stellar Chaos (12 Jun 2013)
Nearly a decade ago, the Chandra X-ray Observatory caught signs
of what appeared to be a black hole snacking on gas at the middle of the
nearby Sculptor galaxy (NGC 253). Now, NuSTAR has taken a peek at this
starburst galaxy, and found the black hole is currently "asleep", according
to Lehmer
et al. (2013, ApJ, in press).
