| Outline of Final Research Achievements |
The high precision analyses of the new data from the IceCube Neutrino Observatory have been conducted. We have successfully obtained the completely new insights on the long-standing mystery of ultra-high energy cosmic ray (UHECR) origins. Our measurements of extremely-high energy neutrinos with energies thousands of trillions higher than visible light have revealed that UHRCRs are unlikely to originate in powerful super-luminous objects mainly found in the far-universe, ruling out the classical belief on the UHECR origins. The results also favor that the main populations of UHECR compositions are nuclei heaver than protons. We have also established the cosmic neutrino signal realtime identification methods, which enables rapid follow-up observations by various astronomy instruments prompted by a cosmic neutrino detection. This new approach has led to the first identification of a high energy neutrino source candidate.
