Probing the extreme universe with multi-messenger astrophysics
Abstract
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is an innovative probe mission designed to observe cosmic neutrinos above 20 PeV and ultra-high energy cosmic rays above 20 EeV over the full sky. The POEMMA mission calls for two identical satellites flying in loose formation, each comprised of a 4-meter wide field-of-view (45 degrees) Schmidt photometer. The hybrid focal surface includes a fast (1 μs) ultraviolet camera for fluorescence observations and an ultrafast (10 ns) optical camera for Cherenkov observations. POEMMA will provide new multi-messenger windows (neutrinos and cosmic rays) onto the most energetic transient events in the universe, enabling the study of new astrophysics and particle physics at these otherwise inaccessible energies.
