Gamma Ray Science Interest Group
The goal of the Gamma Ray Science Interest Group (GRSIG) 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 GRSIG 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 GRSIG is open to all members of the community. If you are interested in contributing to the work of the GRSIG, please subscribe using the link below. You can contact the GRSIG members
