First TDAMM SIG Virtual Meeting March 1, 2:00pm ET

23 February 2024

The first virtual meeting of the Cross-PAG Time-Domain and Multi-Messenger Science Interest Group (TDAMM SIG) will be on Friday 1 March at 2p Eastern (11a Pacific).

We will begin our roughly monthly virtual series with a discussion on the specific TDAMM recommendations to NASA from the most recent Astrophysical Decadal Survey report, “Pathways to Discovery in Astronomy and Astrophysics for the 2020s,” with a relevant individual from the Decadal. This will be followed with a broader discussion on this topic as well as the goals of TDAMM SIG in general.

The details for this meeting and those in the future will be announced over the TDAMM SIG mailing list, which you can sign up for on the SIG’s sign up page.

Time Domain and Multi-Messenger Initiative

The Astro2020 Decadal Report recommended time domain and multi-messenger (TDAMM) astrophysics as the highest-priority sustaining activity in space.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.
