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) radiation in the sub-mm, mm and
- Swift AGN & Cluster Survey (SACS) Total-Band (0.2-10 keV) Point
Source Catalog (06 Jul 2015)
This catalog of 22,563 Swift XRT point sources which were detected
in the total X-ray band (0.2-10 keV) in 125 sq. degrees of serendipitous fields
(from Dai et al. 2015, ApJS, 218, 8) is now available in
Browse and Xamin, along with the catalogs of
17,748 soft-band (0.5-2.0 keV) point sources,
10,060 hard-band (2-10 keV) point sources and
442 soft-band (0.5-2.0 keV) extended sources which were
presented in the same paper.

- NASA News Feature: Astronomers Predict Fireworks from A Rare Stellar Encounter in 2018 (04 Jul 2015)
Astronomers are gearing up for high-energy fireworks coming in
early 2018, when PSR J2032+4127, a stellar remnant the size of a city, 'meets'
its companion, MT91 213, one of the brightest stars in our galaxy. The cosmic
light show will occur when this pulsar discovered by Fermi reaches periastron
in its orbit about its massive companion.
Scientists plan a global campaign to watch the event, from radio wavelengths to
the highest-energy gamma rays detectable.
- NASA News Feature: NASA Missions Monitor a Waking Black Hole (02 Jul 2015)
NASA's Swift satellite detected a rising tide of high-energy
X-rays from the constellation Cygnus on June 15, just before 2:32 p.m. EDT.
About 10 minutes later, the Japanese experiment on the ISS called the Monitor
of All-sky X-ray Image (MAXI) also picked up the flare. The outburst came from
V404 Cygni, a binary system located about 8,000 light-years away that contains
a black hole. Every couple of decades the black hole fires up in an outburst
of high-energy light, becoming an X-ray nova.
- News Article: Pulsar's Unusual Behavior May Help Scientists Understand Their Fundamental Structure (30 Jun 2015)
Using data from Swift and RXTE, a team led by Frank Marshall of
NASA/GSFC observed that the pulsar B0540-69 radically changed the rate at
which its rotation rate slowed after 12 years of a steady decline. There is
not enough data yet to classify the pulsar as intermittent, but the article
notes that the behavior of this object may help solve the fundamental
questions about what is inside them and why they shine at all.
