The power of multimessenger astrophysics was demonstrated in 2017 through the observation of a binary neutron star merger, the first astrophysical event observed in both the gravitational wave and electromagnetic spectra. Multimessenger astrophysics will remain an important tool for astronomers in the future as we combine electromagnetic radiation, gravitational wave radiation, and particle astrophysics observations of cosmic events. NASA's space observatories in the 2020 decade and beyond will have an important role to play, including those that will continue to operate in the 2020s, such as Hubble, Chandra, Swift, Fermi, those currently planned, including JWST, WFIRST, Athena, LISA, Explorers, and those that will be considered by the 2020 astrophysics decadal committee.
The Multimessenger Astrophysics Science Analysis Group will analyze the potential scientific benefits of multimessenger observations made possible by NASA observatories in the 2020 decade and beyond, working in conjunction with each other or with other ground and space-based instruments.

The Multimessenger Astrophysics Science Analysis Group (MMA SAG) would like to offer community members the opportunity to advertise any Decadal Survey White Papers they're considering writing, including if they would like broader participation.
If you are writing or would like write to a Multimessenger Science white paper, please fill out the form at https://docs.google.com/forms/d/e/1FAIpQLSeUOECM0KxPu3OLHcBMOqGknVJNP-fMsKg9hMCoFf0evYFnOQ/viewform. Responses will be monitored and posted to the website at https://pcos.gsfc.nasa.gov/sags/mmasag/whitepapers.php every few business days.
