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.
- xTime tool enhanced (01 Apr 2020)
Support for INTEGRAL Julian Dates has been added. Also, xTime
will now calculate time intervals (in days/hours/minutes/seconds, fractional
days, and total seconds) between successive date/time conversions.
- HEASoft 6.27 Released (31 Mar 2020)
Released March 31, 2020. This release includes updates to NICER
and NuSTARanalysis software only and other fixes/improvements. In particular CFITSIO now interprets parentheses in path names correctly which improves compatibility with files stored on cloud services.
- 2020 NASA Awards Prize Postdoctoral Fellows Selected (30 Mar 2020)
NASA has selected 24 new Fellows for its prestigious NASA Hubble Fellowship Program (NHFP). The program enables outstanding postdoctoral scientists to pursue independent research across NASA Astrophysics, using theory, observation, experimentation, or instrument
development. Each fellowship provides the awardee up to three years
Full biographies and other information about this year's Fellows, including each Fellow's research plans, are available
at this link.
- INTEGRAL AO-18 Proposal Deadline Postponed (30 Mar 2020)
The INTEGRAL AO-18 proposal submission deadline has been postponed from Friday, 3 April to Monday, 4 May 14:00 CEST as result of
the COVID-19 crisis.
ESA will continue to follow developments closely and may provide additional updates in the next weeks,
at the latest by Monday, 20 April.
- Swift-BAT 105-Month All-Sky Hard Band X-Ray Survey (SWBAT105M) released (27 Mar 2020)
The SWBAT105M table includes hard X-ray sources detected
in the first 105-months of observations with the BAT coded-mask imager
on board the Swift observatory and provides 1632 (422 new detections)
hard X-ray sources in the 14-195 keV band above the 4.8 sigma
significance level. This catalog is
now available in Browse and
- NICER follow-up observation and a candidate timing anomaly from Swift J1818.0-1607 (25 Mar 2020)
NICER followup observations of the magnetar candidate Swift J1818.0-1607 imply a spin down age of 310 years based on the period derivative. This makes Swift J1818.0-1607 one of the youngest magnetars known.
