Description

The program supports research that accelerates the synergy between observations and theory in multi-messenger astrophysics, integrating studies using electromagnetic waves, high-energy particles (including neutrinos and cosmic rays), and gravitational waves. Proposals must address at least one of the following: coordination of multi-messenger observations, direct observations of multi-messenger sources, or interpretation (theory, experiment, simulations) of such phenomena. The aim is to build capabilities and foster community-wide interoperability, enabling fundamentally new explorations of the universe. Projects that develop a skilled workforce in this field or integrate research communities are encouraged. The program is not a replacement for existing single-messenger programs but is intended for proposals with significant multi-messenger components.
