SUMMARY:POEMMA: the Probe of Extreme Multi-Messenger Astrophysics
DESCRIPTION:The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) has been designed to measure ultra-high energy cosmic rays (UHECRs) and observe cosmic neutrinos from space and with sensitivity over the full celestial sky for these extremely energetic cosmic messengers. POEMMA will observe the extensive air showers (EASs) from UHECRs and UHE neutrinos above 20 EeV via air fluorescence. Additionally\, for cosmic neutrinos above 20 PeV POEMMA will observe the Cherenkov signal from upward-moving EASs induced by Earth-interacting tau neutrinos. The POEMMA spacecraft are designed to quickly re-orientate to view neutrino transient sources and follow these to obtain unparalleled neutrino flux sensitivity. POEMMA represents the final goal of the JEM-EUSO program. Developed as NASA Astrophysics Probe-class mission\, POEMMA consists of two identical satellites flying in loose formation and 525 km altitude orbits. Each POEMMA instrument incorporates a wide field-of-view (45°) Schmidt telescope with over 6 m2 of collecting area. The hybrid focal surface of each telescope includes a fast (1 ms) near-ultraviolet camera for EAS fluorescence observations and an ultrafast (10 ns) optical camera for Cherenkov EAS observations. In a 5-year mission\, POEMMA will provide measurements that open new multi-messenger windows onto the most energetic events in the universe\, enabling the study of new astrophysics and particle physics at these otherwise inaccessible energies. During this seminar the mission science and design will be reported as well as the path towards its realization. \n  \nMore ways to join: \nJoin from the meeting link \nhttps://infn-lnf.webex.com/infn-lnf/j.php?MTID=ma031e54bc19051e8c5150052f6167d0e \nJoin by meeting number \nMeeting number (access code): 163 849 1504\nMeeting password: awGxvNeK338
