The IceCube observatory, a cosmic neutrino detector located in the South Pole at a depth of about 3500 m, is the first and largest operating km3 neutrino telescope on the Earth. The IceCube’s discovery of neutrino events of cosmic origin in the TeV-PeV energy range stated the beginning of the age of neutrino astronomy.
The ANTARES telescope was the first operational Neutrino Telescope in the...
IceCube is a cubic-kilometer Cherenkov telescope operating at the South Pole. In 2013, IceCube discovered high-energy astrophysical neutrinos and has more recently found compelling evidence for a flaring blazar being a source of high-energy neutrinos. However, as the gamma-ray blazars detected in the GeV energy band can only be responsible for a small fraction of the observed cosmic neutrino...
The sources of the astrophysical neutrino flux discovered by IceCube remain for the most part unresolved. Extragalactic core-collapse supernovae (CCSNe) have been suggested as potentially able to produce high-energy neutrinos. In recent years, the Zwicky Transient Facility has discovered a population of exceptionally luminous supernovae, whose powering mechanisms have not yet been fully...
Upcoming neutrino telescopes may discover ultra-high-energy (UHE) cosmic neutrinos, with energies beyond 100 PeV, in the next 10--20 years. Finding their sources would expose the long-sought origin of UHE cosmic rays. We search for sources by looking for multiplets of UHE neutrinos arriving from similar directions. Our forecasts are state-of-the-art, geared at neutrino radio-detection in...
The IceCube Neutrino Observatory located at the geographic South Pole is composed of two detectors. One is the in-ice optical array, which measures high-energy muons from air-showers and charged particles produced by the interaction of high-energy neutrinos in the ice. The other is an array of ice-Cherenkov tanks at the surface, called IceTop, which is used both as veto for the in-ice neutrino...
