Estimated 200 awards; award size and duration vary by project and program.

Supports research integrating electromagnetic, high-energy particle, and gravitational wave observations to advance multi-messenger astrophysics.

--- ## 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. --- ## Due Dates - September 30, 2026 (Final submission deadline) Proposals may be submitted to relevant participating NSF programs until the listed closing date. --- ## Funding Amount - Approximately 200 awards are anticipated. - Award size and duration vary according to the specific project and participating program. - No cost sharing or matching is required. --- ## Eligibility - Open to all applicants (“Unrestricted”). - Typical eligible organizations include universities, colleges, non-profit and for-profit organizations, and other research institutions. - Proposals must be submitted to relevant participating NSF programs and must address at least one criterion: coordination, observations, or interpretation of multi-messenger astrophysical phenomena. --- ## Application Process - Proposals should be prepared and submitted according to the [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg). - Submit proposals to the relevant NSF program listed under "Related Programs" on the program page. - The proposal title must begin with "WoU-MMA:" to be considered under this program. - Supplement requests to existing NSF awards that newly address multi-messenger astrophysics are also considered. - Ensure compliance with updated NSF research security policies and requirements. --- ## Additional Information - Proposals not meeting the multi-messenger criteria will be reviewed within the context of the standard program to which they are submitted. - Priority is given to proposals that significantly advance the goals of multi-messenger astrophysics. - The program is administered by the Division of Astronomical Sciences (AST), Division of Physics (PHY), and the Office of Polar Programs (OPP). --- ## External Links - [Program Description and Application Instructions](http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=505593) - [NSF Program Page](https://www.nsf.gov/funding/opportunities/wou-mma-windows-universe-era-multi-messenger-astrophysics) - [NSF Proposal & Award Policies & Procedures Guide (PAPPG)](https://www.nsf.gov/policies/pappg/24-1) - [Browse Recent Awards](https://www.nsf.gov/awardsearch/advancedSearchResult?ProgEleCode=011Y00%2C123300%2C124200%2C124400%2C125200%2C128500%2C128800%2C160900%2C164300%2C167800%2C511500&BooleanElement=Any&BooleanRef=Any&ActiveAwards=true#results) - [Map of Recent Awards](https://tableau.external.nsf.gov/views/ProgramAwards/Summary?pims_id=505593&embed=y&%3AisGuestRedirectFromVizportal=y&%3Atoolbar=no&Fpec=011Y00%2C123300%2C124200%2C124400%2C125200%2C128500%2C128800%2C160900%2C164300%2C167800%2C511500) --- ## Contact Information | Name | Email | Phone | Division | |-----------------------|-------------------------------------|---------------|--------------| | Hans A.
