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 data
obtained by high-energy astronomy missions observing in the
extreme-ultraviolet (EUV), X-ray, and gamma-ray bands, as well as 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
The HEASARC is a member of the NASA Astronomical
Virtual Observatories (NAVO) where we work with other NASA archives to
ensure comprehensive and consistent VO access to NASA mission datasets.
Users may now query the HEASARC's catalogs using VO-enabled services and
specialized tools. This page describes
how to get to the HEASARC VO-enabled
services and provides information on other HEASARC VO activities.
- AstroSat Data is now public (28 Sep 2018)
AstroSat data was opened to public on September 26,
2018. Around 25% of the AstroSat (around 1TB) data from the four
payloads, UVIT, SXT, LAXPC and CZT is available for download from the Indian
Space Science Data Centre . This data provide an exciting opportunity in understanding the cosmos from UV to X-rays through out the world.
- MAXI CALDB installed at the HEASARC (25 Sep 2018)
The 20180912 version of the MAXI CALDB is now installed and available at the HEASARC. This is the first official release of the MAXI Calibration Database. MAXI CALDB Users will need to update their $CALDBCONFIG to the latest version (caldb.config.20180925)
- IGR J17591-2342 second re-brightening observed with NICER (21 Sep 2018)
NICER observations of the second re-brightening of the accreting millisecond pulsar IGR J17591-2342 show it reaching its highest flux yet seen, with strong pulsations remaining after almost 60 days post-outburst.
- 12th INTEGRAL Workshop and 1st AHEAD Gamma-Ray Workshop (19 Sep 2018)
The 12th INTEGRAL Conference will be organized together with the 1st AHEAD Gamma-Ray Workshop on 11-15 February 2019:
"INTEGRAL looks AHEAD to Multi-Messenger Astrophysics".
It will be hosted by the Campus Biotech, in Geneva (Switzerland).
This conference will discuss recent developments in high-energy astronomy,
with particular emphasis on its role in multi-messenger astronomy.
Further information including deadlines can be found at the above link.
- Viewing tool updated (17 Sep 2018)
The Swift pole constraints have been updated in the Viewing
tool. The revised coefficients extrapolate the trend for the next year. The
Viewing tool now also can report a "preferred" visibility window for NICER
observations, which has a Sun angle constraint of 60-180 degrees. (The nominal
visibility window for NICER observations is unchanged.)
- PIMMS updated to Version 4.9 (17 Sep 2018)
Version 4.9 contains updates for NICER rate simulations and updated calibrations for XMM....
