HEACIT Working Group

High Energy Astrophysics Codes, Interface, and Tools Working Group

September 7, 2021

HEACIT is a community-run organization independent of NASA but for which HEASARC provides web hosting for the convenience of the community.


The HEACIT collaboration is a working group that seeks to identify how the landscape of astrophysical software enables or can improve the impact of high energy astrophysical data. This includes maximizing the return of current and future observations, as well as increasing their usability and interoperability with datasets at other wavelengths.

HEACIT is not technically associated with any particular software package, but HEACIT members include developers of high energy software packages such as XSPEC, SPEX, Sherpa, and ISIS. The goal of the working group is to connect developers, align on standard practices and collaborate on future development, while allowing for and preserving the diversity of available high energy tools and workflows.

See the HEACIT Charter for details regarding HEACIT goals, organizational structure, tasks, and practices.


The current HEACIT Chair is Lia Corrales. The HEACIT Steering Committee includes the HEACIT Chair, Randall Smith, Tess Jaffe, and Michael Wise.

Nominations should be sent directly to the HEACIT Chair, who will then review it with the Steering Committee. Nominations must include:

  • A statement that the applicant agrees to abide by the HEACIT Charter
  • A description of the applicant's scientific background, research interest and expertise, and expected/planned contribution to HEACIT
Self-nominations are allowed and encouraged.
