Science Analysis Groups (SAGs)

Completed SAGS

• The Gamma-ray Transient Network Science Analysis Group (GTN SAG). The emphasis on time-domain and multimessenger astronomy by Pathways to Discovery in Astronomy and Astrophysics for the 2020s, the Astro2020 Decadal report, led to this Science Analysis Group tasked with quantifying what could and should be done with the InterPlanetary Network (IPN). The final report was submitted by the SAG in 2023.
• The Technology Science Analysis Group (TechSAG) was very active during the first year of the PhysPAG. It providing broad community inputs to NASA PhysCOS technology planning. The TechSAG work was completed (summer 2012) and moved to the four continuing SAGs (IPSAG, X-ray SAG, GWSAG, and GammaSAG). The four continuing SAGs were later redesignated as Science Interest Groups (SIGs): IP SIG, XR SIG, GW SIG, and GR SIG.
• TDAMM Communications SAG Contacts: Co-Chairs Jamie Kennea (Penn State) and Judy Racusin (NASA GSFC).

Completed Cross-PAG SAGs

• The Multimessenger Astrophysics Science Analysis Group (MMA SAG) analyzed the potential scientific benefits of multimessenger observations made possible by NASA observatories in the 2020 decade and beyond, working in conjunction with each other or with other ground and space-based instruments. This SAG concluded activities in 2020.
