The goal of the Gamma Ray Science Interest Group (GR SIG) is to provide quantitative metrics and assessments to NASA in regard to current and future needs of hard X-ray and gamma-ray astrophysics community. Specifically, the activities of the GR SIG include:
Act as a focal point and forum for the hard X-ray and gamma ray communities.
Organize bi-weekly telecons to discuss recent science results, and current and future missions.
Maintain a list of technology needs for future hard X-ray and gamma-ray missions.
Produce suggestions to help support the specific needs of this unique community: organizational, scientific, funding.
The GR SIG is open to all members of the community. If you are interested in contributing to the work of the GR SIG, please subscribe using the link below.

NASA Missions Study What May Be a 1-In-10,000-Year Gamma-ray Burst
On Sunday, Oct. 9, 2022, a pulse of intense radiation swept through the solar system so exceptional that astronomers quickly dubbed it the BOAT – the brightest of all time. The source was a gamma-ray burst (GRB), the most powerful class of explosions in the universe. Read more.
