Opened Windows to Universe – The Observation of an ultra-high-cosmic Neutrino

Abstract:
On February 23, 2023, the ARCA neutrino telescope of the KM3NeT collaboration detected a cosmic neutrino with an ultra-high energy in the hundreds of PeV range (1 PeV = 10^15 eV). This represents a breakthrough discovery in the fields of astronomy and astrophysics, significantly advancing our understanding of the universe. The operation and further construction of neutrino telescopes, such as Baikal-GVD, IceCube, KM3NeT, and P-ONE, progressively realize neutrino astrophysics' goals. New neutrino telescope projects, including HUNT and TRIDENT, are being developed in China. Observing galactic and extragalactic neutrinos enables researchers to gain insights into high-energy cosmic rays, gamma-ray bursts, and distant objects like active galactic nuclei. It also helps to explore unique processes in the universe, such as supernova explosions, colliding stars and galaxies, and black hole collisions.
