The HAWC telescopes has recently revealed new spectra for gamma-ray sources in the Galactic plane. In this talk I will review the possibility of detecting these sources at KM3 detectors. I will consider, with particular emphasis, the 2HWC J1825-134 source. Amongst the HAWC sources, it is indeed the most luminous in the multi-TeV domain and
therefore is one of the first that should be searched...
Recently, evidence for an association between high energy neutrinos detected by
IceCube and radio-selected blazars has been found by Plavin et al. (2020, 2021). This result was achieved using an all sky complete sample of 3411 blazars selected on their parsec-scale flux density at 8 GHz higher than 150 mJy. We perform an analysis using the same sample of radio-selected blazars and search for a...
The IceCube Neutrino Observatory has detected high-energy astrophysical
neutrinos in the TeV-PeV range. These neutrinos have an isotropic
distribution on the sky, and therefore likely originate from extragalactic
sources. Active Galactic Nuclei (AGN) form a class of astronomical objects
which are promising neutrino source candidates given their high
electromagnetic luminosity and potential...
Muons and neutrinos created by cosmic rays interacting in the atmosphere create a significant background for IceCube astrophysical neutrinos in the southern sky. However, looking for neutrino events that start in the detector can reduce both the atmospheric muon and atmospheric neutrino background while retaining the astrophysical neutrino signal. The method presented here results in a higher...
Baikal-GVD is a next generation, kilometer-scale neutrino telescope currently under construction in Lake Baikal. GVD is formed by multi-megaton subarrays (clusters) and is designed for the detection of astrophysical neutrino fluxes at energies from a few TeV up to 100 PeV. The design of Baikal-GVD allows one to search for astrophysical neutrinos with flux values measured by IceCube already at...
The Baikal-GVD detector currently consists of 2016 optical modules arranged on 56 vertical strings in a water volume of 0.35 km$^3$. The data from the partially complete array have been analyzed using a $\chi^2$-based track reconstruction algorithm. After a zenith angle cut and other background suppression cuts, a sample of upgoing neutrino candidate events is obtained. The analysis is...
The next generation of neutrino telescopes, including Baikal-GVD, KM3NeT, P-ONE, TAMBO, and IceCube-Gen2, will be able to determine the flavor of high-energy astrophysical neutrinos with 10% uncertainties. With the aid of future neutrino oscillation experiments --- in particular JUNO, DUNE, and Hyper-Kamiokande --- the regions of flavor composition at Earth that are allowed by neutrino...
The Glashow resonance describes the resonant production of a W− boson during
the interaction of an electron antineutrino with an electron.
The cross-section of this process peaks at an antineutrino energy of 6.3 petaelectronvolts (PeV) in the rest frame of the electron.
In this talk, I will report on the observation by the IceCube Neutrino Observatory of a neutrino-induced particle shower with...
The ANTARES neutrino telescope, located in the Mediterranean Sea, is the longest-operated under-sea neutrino detector, having collected data for more than 14 years and since 2008 in its full configuration. These data have been used to search for a diffuse flux of cosmic neutrinos, upgrading previously published results both in terms of livetime and in search method. In particular, a new event...
The identification of cosmic objects emitting high energy neutrinos could provide new insights about the Universe and its active sources. The existence of these cosmic neutrinos has been proven by the IceCube collaboration, but the big question of which sources these neutrinos originate from, remains unanswered. The KM3NeT detector for Astroparticle Research with Cosmics in the Abyss (ARCA),...
