This review demonstrates the unique role of the neutrino by discussing in detail the physics
of and with neutrinos. We deal with neutrino sources, neutrino oscillations, absolute masses …

We present a comprehensive multi-messenger study of NGC 1068, the prototype Seyfert II
galaxy associated with high-energy neutrinos following a detection by the IceCube Neutrino …

The origin of high-energy cosmic rays, atomic nuclei that continuously impact Earth's
atmosphere, is unknown. Because of deflection by interstellar magnetic fields, cosmic rays …

A supermassive black hole, obscured by cosmic dust, powers the nearby active galaxy NGC
1068. Neutrinos, which rarely interact with matter, could provide information on the galaxy's …

The IceCube Neutrino Observatory has established the existence of a high-energy all-sky
neutrino flux of astrophysical origin. This discovery was made using events interacting within …

We present a measurement of the high-energy astrophysical muon–neutrino flux with the
IceCube Neutrino Observatory. The measurement uses a high-purity selection of650k …

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy
physics. With energies far beyond solar, supernovae, atmospheric, and accelerator …

The origins of the high-energy cosmic neutrino flux remain largely unknown. Recently, one
high-energy neutrino was associated with a tidal disruption event (TDE). Here we present …

Cosmic neutrinos provide a unique window into the otherwise hidden mechanism of particle
acceleration in astrophysical objects. The IceCube Collaboration recently reported the likely …

The Pacific Ocean Neutrino Experiment is a new initiative towards constructing a multi-cubic-
kilometre neutrino telescope to expand our observable window of the Universe to the …
