ANTARES and IceCube combined search for neutrino point-like and extended sources in the southern sky

Abstract:

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 effectively not absorbed while traveling through cosmological distances and can escape from dense astrophysical environments. These qualities make them ideal cosmic messengers as they point back to their production sites. Several classes of astrophysical objects, such as supernova remnants, pulsar wind nebulae, and active galactic nuclei (AGNs) have been indicated as promising high-energy neutrino source candidates (Gaisser et al. 1995; Halzen & Hooper 2002; Becker 2008; Kelner & Aharonian 2008; Murase 2015). Neutrinos are expected to be produced through the decay of charged mesons, a result of hadronic interactions of accelerated protons with matter or radiation in the surroundings of the acceleration sites …
