Description
Hadronic processes should exist in sources but most information we have until now on the Universe comes from electromagnetic processes and they are conveyed by photons. Neutrinos offer a chance to observe regions up to tens of Gpc and can bring information on the acceleration processes of the most powerful engines of the universe, like gamma-ray bursts and active galactic nuclei.
I will go through the most recent results on the hunt for point-sources of neutrinos with particular attention to IceCube in the Antarctic ice depths and ANTARES in the sea abyss in front of Toulon. I will discuss the importance of the observation of astrophysical neutrinos, at what level of fluxes we expect to see some signal, an the power of methods we have implemented to deal with low statistics signals on top of large backgrounds from atmospheric particles.
I also will discuss particle physics results that we are deriving using an unprecedented statistics of atmospheric neutrinos and muons. This measurement is useful to explore kinematic regions not accessible by colliders and fixed target experiments.
