ROSES-25 D.4 Theoretical and Computational Astrophysics Networks. NoIs due 15 October 2026
3 September 2026
The ROSES-25 program element D.4 Theoretical and Computational Astrophysics Networks (TCAN) 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 boundaries and advance the training of the future workforce of theoretical and computational scientists.
For this program element, the TCAN program focuses its scope on grand challenges in Time Domain Multi-Messenger Astrophysics, and solicits proposals aimed at developing integrated theoretical and computational tools for modeling multi-messenger phenomena through collaborative networks.
It is expected that the proposing networks will include participants with complementary expertise in different topical areas, such as astrophysics, gravitational physics, nuclear physics, plasma physics, computational mathematics, numerical methods and algorithms, software engineering, and/or space- and ground-based observational astronomy. Multi-disciplinary collaboration spanning various sectors (e.g., academic, national laboratory, and private organizations, among others) are encouraged.
ROSES-2025 Amendment 70 releases D.4 TCAN as a new opportunity in ROSES-25. Mandatory Notices of Intent are due by 15 October 2026, and proposals are due by 3 December 2026.
