Physics of the Cosmos Sessions
The PhysPAG session will be a community brainstorming session focusing on “Physics of Cosmos in the 2030s and Beyond: Science, Missions, and Innovations Shaping the Future of NASA Astrophysics.”
The joint meeting of the program analysis groups (PAGs) – for PhysCOS (PhysPAG), Cosmic Origins (COPAG), and Exoplanet Exploration (ExoPAG) - will include updates from the HWO, TDAMM, and AI/ML SIGs and a discussion with Shawn Domagal-Goldman (director of NASA Astrophysics) and the PAG Executive Committee chairs.
Other Sessions of Interest about Physics of the Cosmos SessionsThe 247th AAS meeting (joint with the Historical Astronomy Division) will be held 4-8 January in Phoenix, Arizona at the Phoenix Convention Center.
