ACROSS: Enabling Time Domain and Multi-Messenger Astrophysics with NASA Missions

The Astro2020 Decadal Survey recommended an investment in Time Domain and Multi-Messenger Astrophysics (TDAMM) as the top-priority sustaining activity in space for the coming decade. One aspect of NASA’s response to this recommendation is a pilot project, the Astrophysics Cross-Observatory Science Support (ACROSS) initiative, designed to provide support to both missions and observers as they pursue TDAMM science. Here, we present our observations of needs in the community and initial plans for ACROSS activities, including services to facilitate and improve cross-observatory follow-up planning and execution; a multi-messenger web portal with links to existing observatory resources, community tools, and information targeted for TDAMM General Observers.

Speaker: Samuel Wyatt (NASA/GSFC)

This event will be held in person in STScI's Café Con and virtually. To stream the colloquium, please click the Webcast button above. 

The goal of STScI Engineering and Technology Colloquia is to provide speakers for our community of the highest caliber from leading-edge engineering and technology disciplines and promote collaboration with professionals across the Institute. The steering committee invites speakers not only from conventional engineering disciplines, but from across business, academia, and government. Obtaining speakers with perspectives and knowledge that can enrich the understanding of our staff and simultaneously enhance their connections with other professionals across the nation is fundamental to ensuring STScI remains at the forefront of its mission.
