IceCube has discovered a flux of astrophysical neutrinos and presented evidence for the first neutrino sources, a flaring blazar known as TXS 0506+056 and the active galaxy NGC 1068. However, the sources responsible for the majority of the astrophysical neutrino flux remain elusive. High-energy neutrinos can be produced when cosmic rays interact at their acceleration sites and during...

The ANTARES neutrino telescope was located in the Mediterranean Sea, not far from Toulon (France). It was operational from 2007 to 2022, before being dismantled. Its instrumented volumeof 0.01 km$^3$ equipped with photomultipliers made it possible to detect neutrinos with energy from some GeV to PeV. The location of ANTARES allows for an advantageous view of the Southern sky in the search of...

The discovery of a high energy neutrino from IceCube coincident in time with flaring activity in gamma-rays from TXS 0506+056 solidified neutrinos as an integral part of the emerging field of multimessenger astrophysics. From the direction of the source, an archival neutrino flare was also identified and contributed to the significance of TXS 0505+056 as a neutrino source. An alert stream for...

Three new analyses related using old Kamiokande data recorded in 1987 are reported.
Go to contribution page
The first analysis is for 11 neutrino events in the Kamiokande-II SN1987A data. It is well known that there is a seven second gap between the 9th and 10th event. It is pointed out that no cosmic ray muon event with a rate of 0.37 Hz was detected during this period. Furthermore, no low-energy background event,... -

Evidence for the existence of dark matter strongly motivates the efforts to study its unknown properties. Additionally, the origin of high-energy astrophysical neutrinos detected by IceCube remains uncertain. If dark matter and neutrinos couple to each other, we can search for a non-zero elastic scattering cross section. The interaction between an isotropic extragalactic neutrino flux and dark...

DarkSide-20k (DS-20k) will probe the dark matter WIMP hypothesis by looking for WIMP-nucleon elastic scattering with a dual-phase time projection chamber (TPC) detector filled with 50 tonnes of low-radioactivity liquid argon extracted from underground sources. Besides the primary physics goal of DS-20k, the low-energy threshold (of about 0.5 keV for nuclear recoils) of the detector will allow...

IceCube recently observed neutrino emission from the nearby active Seyfert galaxy NGC 1068 in the TeV energy range. This finding suggests that active galactic nuclei (AGN) could be a source type contributing to the diffuse high-energy astrophysical neutrino flux. The dense environments near the supermassive black holes and the acceleration of cosmic rays in the coronae offer suitable...
