Description
The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) has been
recently selected by NASA for an in-depth probe mission concept study
in preparation for the next decadal survey. POEMMA will combine the
well-developed Orbiting Wide-field Light collectors (OWL) concept with
the recently proposed CHerenkov from Astrophysical Neutrino Telescope
(CHANT) concept to form a multi-messenger probe of the most extreme
environments in the universe. POEMMA is designed to establish charged
particle astronomy with ultrahigh energy cosmic rays (UHECRs) and to
discover cosmogenic tau neutrinos (CTNs). The study of UHECRs and
CTNs from space will yield orders-of-magnitude increase in statistics
of observed UHECRs and the discovery of the cosmogenic flux of
neutrinos for the full predicted range of UHECR models. These
observations will solve the long-standing puzzle of the origin of the
highest energy particle ever observed, providing a new window on the
Universe and on its most energetic environments and events. The
discovery of CTNs will help solve the puzzle of the origin of UHECRs
and begin a new field of Astroparticle Physics with the study of
neutrino properties at energies up to the 10 EeV scale.
