A View of the Universe with the IceCube and ANTARES Neutrino Telescopes

Cosmic rays and neutrinos are intimately related. And though TeV-PeV astrophysical neutrinos have been observed, their sources and their relation to potential sources of cosmic rays remain unknown. Two current under-water/ice neutrino observatories, ANTARES and IceCube, have conducted numerous searches from potential neutrino sources. In this presentation I will describe the characteristics of the observed neutrino spectrum. I will showcase specific studies of potential neutrino sources of both galactic and extragalactic nature. I will review the multi-messenger aspect of the field, especially in relation to the search for electromagnetic counterparts to neutrino sources. Finally, I will describe real-time activities that enable the multi-messenger studies.
