HEA Tools and Resources

astro piciture

The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for high-energy astronomy missions, in the extreme ultraviolet, X-ray and gamma-ray wavelengths. The HEASARC provides archival data, multi-mission software and analysis tools, and information about current and past observatory missions. The HEA Division is a partner in the HEASARC with NASA's GSFC.

ADS logo

The Astrophysics Data System (ADS) is a NASA-funded project which maintains three bibliographic databases containing more than 5.3 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through our Abstract Service query forms, and full-text scans of much of the astronomical literature which can be browsed though our Browse interface.

AtomDB logog

AtomDB consists of a large selection of atomic data relevant to X-ray astronomy, covering elements from H to Zn. In addition, it is connected to a collisional plasma code that produces the APEC models widely used in fitting packages such as XSPEC and Sherpa. Online access to the data is provided through the WebGUIDE interface, and an iPad app is available.

The High Energy Astrophysics Division has as a major activity the provision of new software to enable astrophysics research. The main focus of this is the Chandra X-ray Center Data Systems Division, but significant contributions come from other groups in HEA.
