Search for the astrophysical sources of the Fly's Eye event with the highest to date cosmic ray energy E=3.2·10²⁰ eV
Among the registered extremely high energy cosmic rays (EHECR, E > 10²⁰ eV) an event with the highest to date energy of E = 3.2 · 10²⁰ eV was detected by the Fly's Eye experiment (FE event) in 1991. With the use of the back-tracking method for the calculation of the EHECR trajectories in Gal...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Among the registered extremely high energy cosmic rays (EHECR, E > 10²⁰ eV) an event with the highest to date energy of E = 3.2 · 10²⁰ eV was detected by the Fly's Eye experiment (FE event) in 1991. With the use of the back-tracking method for the calculation of the EHECR trajectories in Galactic and extragalactic magnetic fields, we show that the galaxies UGC 03574 and UGC 03394 are the most promising candidates among the nearby extragalactic sources for the cases of iron and C-N-O group primary nucleus respectively. The most likely accelerating mechanisms are the newly-born millisecond pulsars, magnetar ares and tidal disruption events in these galaxies. |
