The IceCube collaboration has detected an extraterrestrial neutrino flux with the most significant signal in the southern sky at PeV energies. In spite of its smaller volume, the ANTARES telescope provides comparable sensitivity and superior angular resolution at the given southern declinations and energies below ~100TeV and is thus the ideal instrument to constrain the neutrino spectrum of...

We have performed a new measurement of the all-sky diffuse flux of high energy, E>10TeV, extraterrestrial neutrino induced showers (cascades) based on IceCube data collected during 641 days in 2010--2012. Cascades arise predominantly in electron and tau neutrino interactions and have good energy resolution, so that they are well-suited for the spectral characterization of the extraterrestrial...

Compelling evidence of the existence of cosmic neutrinos has been reported by the IceCube collaboration. Some features of this signal could be explained by a Northern/Southern sky asymmetry of the flux. This possible asymmetry would be related to the presence of the bulk of our Galaxy in the Southern sky.
The ANTARES neutrino telescope, located in the Mediterranean Sea, consists of a three...

The Large Volume Detector (LVD) in the INFN Gran Sasso National
Laboratory, Italy, is a 1 kton liquid scintillator neutrino observatory
mainly designed to study low energy neutrinos from gravitational stellar
collapses. LVD is sensitive to core-collapse supernovae via neutrino
burst detection with 100\% efficiency over our own entire Galaxy.
The result of the search of neutrino bursts...

The IceCube Collaboration measured an all-flavor, high-energy astrophysical neutrino flux. In order to identify the sources of this flux, high-energy muon neutrinos are ideal messenger particles because of their excellent angular resolution. However, the first step is to confirm the observed flux in the muon neutrino channel using IceCube data from 2009 through 2014. The main background for...

With the discovery of a high-energy astrophysical neutrino flux, the IceCube Neutrino Observatory, located at the geographical South Pole, has opened the field of neutrino astronomy. While evidence for extraterrestrial neutrinos has been found in multiple searches, it was not yet possible to identify their sources; they appear as an isotropic excess. Nevertheless, it is possible to constrain...

The Fermi Bubbles are two giant lobes of $\gamma$-ray emission above and below the Galactic Center. Whereas the origin of the observed $\gamma$-ray flux remains obscure, the measurement of a neutrino flux from the Fermi Bubbles could distinguish between leptonic and hadronic emission scenarios.
Such a search for a neutrino signal from the Fermi Bubbles has been performed with the ANTARES...
