The 4th TDAMM Workshop October 27 – 30th 2025

24 July 2025

NASA's new Astrophysics Cross-Observatory Science Support (ACROSS) initiative is organizing the 4th Time Domain and Multi-Messenger Astrophysics (TDAMM) Workshop. This workshop will focus on developing community observing plans to enable the rapid and coordinated follow-up of explosive transients by space-based and ground-based observatories. NASA invites US and international members of the ground and space science communities to attend the workshop and contribute to its final product, a publicly available white paper with findings for relevant agencies and the broader astrophysics community.
4th TDAMM Workshop: Advancing Community Observing Plans for Rapid Follow-Up of Explosive Transients. The workshop will be held 27 – 30 October 2025 in Huntsville, Alabama. We are planning on opening registration in early August.
You can find more information on the workshop and booking accommodation on the workshop website.
For NASA participants, NCTS registration will need to be done by 28 August (search for NCTS code 51567-26).

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
