The National Science Foundation is offering a grant opportunity titled "Multi-Messenger Coordination for Windows on the Universe". This grant aims to support the development of pathways or networks to increase the coordination and optimization of follow-up observations for Multi-Messenger Astrophysics (MMA) campaigns. The astrophysics community has a diverse and powerful network of ground- and space-based instruments and facilities to identify electromagnetic signatures of MMA events and monitor their evolution. However, there is a need to better harmonize these resources and interconnect users. The grant seeks to address this need by facilitating the coordination and optimization of follow-up observations for MMA campaigns. The total program funding is $7,500,000, and it is expected to award 5 grants. The closing date for proposal submission is May 13, 2024. For more information, please visit the NSF Publication 24-542.
