We present evidence that TXS 0506+ 056, the first plausible non-stellar neutrino source,
despite appearances, is not a blazar of the BL Lac type but is instead a masquerading BL …

After the identification of the gamma-ray blazar TXS 0506+ 056 as the first compelling
IceCube neutrino source candidate, we perform a systematic analysis of all high-energy …

In this review paper, we present the main aspects of high-energy cosmic neutrino
astrophysics. We begin by describing the generic expectations for cosmic neutrinos …

KM3NeT will be a network of deep-sea neutrino telescopes in the Mediterranean Sea. The
KM3NeT/ARCA detector, to be installed at the Capo Passero site (Italy), is optimised for the …

Clusters of galaxies can potentially produce cosmic rays (CRs) up to very high energies via
large-scale shocks and turbulent acceleration. Due to their unique magnetic-field …

The existence of high-energy astrophysical neutrinos has been unambiguously
demonstrated, but their sources remain elusive. IceCube reported an association of a 290 …

A search for astrophysical pointlike neutrino sources using the data collected by the
ANTARES detector between 2007 January 29 and 2017 December 31 is presented. A …

Neutrinos are stable, neutral, and weakly interacting particles and, in contrast to cosmic rays,
they are not deflected by magnetic fields. Differently from high-energy photons, neutrinos are …

We derive stringent constraints on neutrino speed, weak equivalence principle violation,
Lorentz invariance violation, and dual lensing from the first high-energy astrophysical …

By constantly monitoring a very large portion of the sky, neutrino telescopes are well-
designed to detect neutrinos emitted by transient astrophysical events. Real-time searches …
