ROSES-25 D.4 Theoretical and Computational Astrophysics Networks TBD Update

15 April 2026

The Theoretical and Computational Astrophysics Networks (TCAN) program element D.4 of ROSES-25 supports coordinated efforts in fundamental theory and computational techniques to make advances in astrophysics that extend beyond the scope of individual investigator projects. The goals of the TCAN program include strengthening theoretical and computational astrophysics in the United States by uniting researchers in collaborative networks that cross institutional and geographical divides and advancing the training of the future workforce of theoretical and computational scientists. For this program element, TCAN will focus its scope to address grand challenges in Time Domain Multi-Messenger Astrophysics (TDAMM).

The TBD placeholder for this program has been updated to reflect the new focus on time domain multi-messenger astrophysics, supporting efforts to advance integrated, multi-scale, multi-physics modeling of these phenomena.

Please direct questions concerning D.4 TCAN to Sanaz Vahidinia at sanaz.vahidinia@nasa.gov.

This cropped horizontal image has layers of semi-opaque rusty red colored gas and dust that starts at the bottom right and goes toward the top left. There are three prominent pillars rising toward the top left. The left pillar is the largest and widest. The peaks of the second and third pillars are set off in darker shades of brown and have red outlines.
