The IceCube project has transformed a cubic kilometer of natural Antarctic ice into a neutrino detector. The instrument detects more than 100,000 neutrinos per year in the GeV-to-PeV energy range. Among those, we have isolated a flux of high-energy cosmic neutrinos. I will discuss the latest measurements of the cosmic neutrino flux and their implications for its possible origin(s). From the...

IceCube is the world's most sensitive neutrino telescope located at the geographic South Pole. With the discovery of a flux of high-energy cosmic neutrinos it has opened a new window for astronomy. Neutrinos allow to study the most extreme environments of our universe even in regions from which photons cannot escape, and help to understand the mechanisms of particle acceleration in the cosmos....

ANTARES, the largest underwater neutrino telescope in the Northern Hemisphere, has been continuously operating since 2007 in the Mediterranean Sea. The transparency of the water allows for a very good angular resolution in the reconstruction of signatures of interactions from neutrinos of all flavors. This results in unprecedented sensitivity for neutrino source searches in the Southern Sky...

Large-scale neutrino telescopes offer interesting possibilities to address particle physics topics ranging from particle searches to neutrino oscillations or tests of fundamental laws. They can even do so at energy ranges not accessible to accelerators, providing a much desired complementarity to accelerator-based physics.

The detection of high energy extra-terrestrial neutrinos by IceCube opens a new window for observations of the Universe. I will discuss the origin of these neutrinos, the clues that their detection provide towards the solution of the long standing question of the origin of cosmic-rays, and the prospects for identifying the cosmic-ray sources and for studying open questions in astro- and...

The atmospheric neutrino flux is produced when cosmic rays collide with Earth's atmosphere. At very high energy, the prompt contribution to the neutrino flux, which comes from decays of charmed hadrons, dominates over the conventional flux, which comes from pion and kaon decays. This is due to the very short lifetime of the charmed hadrons, which therefore do not lose energy before they decay....

Gamma-ray bursts (GRBs) are the most energetic electromagnetic outburst class in the Universe, and candidates for the sources of the ultra-high energy cosmic rays (UHECRs). We discuss the neutrino flux associated with the prompt emission from GRBs, such as its possible contribution to the observed astrophysical neutrino flux, and we show the implications of recent stacking searches for...

Observed spectra of distant blazars show evidence of secondary gamma rays from interactions of cosmic rays with extragalactic photon radiation (EBL and CMB). The same interactions of cosmic rays are expected to produce a flux of neutrinos with energies peaked around 1 PeV. The spectrum and the isotropic distribution are consistent with IceCube observations. This association also implies that...

The recent observation of TeV-PeV neutrinos by IceCube has opened a new window to the high-energy Universe. These high-energy astrophysical neutrinos are expected to originate from cosmic-ray interactions with gas and radiation. The origin of the IceCube signal is presently unknown and various Galactic and extragalactic source candidates have been proposed. Multi-messenger studies can help to...

The riddle of the origin of Cosmic Rays is unsolved since more than one century. The identification of the galactic sources able to accelerate particles beyond PeV energies is certainly one of the main open problems of high energy astrophysics. High energy gamma ray (and neutrino) observations are an essential probe of CRs, if gamma rays (and neutrinos) are produced by CRs interacting close to...

We discuss the capabilities of the present and future observatories in the detection of these secondary particles, that has a paramount importance in constraining models for ultra high energy cosmic rays acceleration.

In the near future, neutrino telescopes are expected to improve their sensitivity to the flux of monochromatic neutrinos produced by dark matter (DM) in our galaxy. This is illustrated by a new limit on the corresponding cross section that we derive from public IceCube data. In this context, we study which DM models could pro- duce an observable flux of monochromatic neutrinos from DM...

The interaction of cosmic rays with the gas contained in our Galaxy is a guaranteed source of diffuse high energy neutrinos. We provide expectations for this component by considering different assumptions for the cosmic ray distribution in the Galaxy which are intended to cover the large uncertainty in cosmic ray propagation models. We calculate the angular dependence of the diffuse galactic...

Also I'll review theoretical models, which can explain observed data both with Galactic and extra-galactic sources of neutrinos. In particular, I'll present model which at the same time explain UHECR and astrophysical neutrinos.

The Galaxy is a guaranteed source of neutrinos produced by the interaction of cosmic rays (CRs) with the interstellar gas. According to conventional CR propagation models, however, this emission may be too weak to be detected even by Km3-scale neutrino telescopes. This expectation has to be revisited in the light of recent Fermi-LAT findings showing that the CR spectrum in the inner Galactic...
