“…In addition, radio emission -nearly constant over 90 days -was found, and was interpreted as due to a mildly relativistic outflow. Theoretical interpretations speculate that the abundant UV photons could be a target for the neutrino production [2], whereas other possible production sites include a disk corona or hidden winds, possibly induced by collisions among tidal streams [3], or the disk itself [4]. Our recent work, Ref.…”

“…In 2019, an IceCube neutrino event (IC191001A) has been associated with the Tidal Disruption Event (TDE) AT2019dsg, with a probability of random coincidence of 0.2% to 0.5% [2]; the neutrino was detected at 150 days after the optical peak of the candidate parent TDE. AT2019dsg was found to be bright in X-rays, which were detected 17 days after peak time with a thermal spectrum with = 60 eV and quickly decayed over a timescale of tens of days.…”

The observation of a neutrino at IceCube in association with the Tidal Disruption Event (TDE) AT2019dsg, has suggested TDEs as a new class of sources of astrophysical neutrinos. We present a model of this multi-messenger observation in a jetted concordance scenario, where the neutrino production is directly linked to the observed X-rays, and the timing of the neutrino observation (about 150 days post peak) can be naturally described. We briefly discuss the implications of our model for future neutrino-TDE associations.

“…Being located in the Northern hemisphere and immersed in sea water, ANTARES can count on a clear visibility of the Southern Sky, and thus of the Galactic Centre, and on a very good angular resolution. This makes it an excellent tool in the search for point-like sources, especially of Galactic origin, and a valid instrument to follow-up the the recent evidence of neutrino emission from the blazar TXS 0506+056 [2,3] and possibly from tidal disruption events (TDEs) AT2019dsg and AT2019fdr [4,5], reported by the IceCube Collaboration. In these proceedings, the results of several searches for point-like sources using 13 years of ANTARES data are presented.…”

The IceCube project transformed a cubic kilometer of transparent natural Antarctic ice into a Cherenkov detector. It discovered PeV‐energy neutrinos originating beyond our galaxy with an energy flux that is comparable to that of GeV‐energy gamma rays and EeV‐energy cosmic rays. These neutrinos provide the only unobstructed view of the cosmic accelerators that power the highest energy radiation reaching us from the universe. The results from IceCube's first decade of operations, foremost the measurement of the diffuse neutrino flux from the universe using multiple techniques is reviewed. The multimessenger data that identified the supermassive black hole TXS 0506+056 as a source of cosmic neutrinos is subsequently reviewed and attention is drawn to accumulating indications that cosmic neutrinos are associated with gamma‐ray‐obscured active galaxies, that is, the energy in gamma rays that accompanies cosmic neutrinos emerges at MeV energies, or below. Reaching beyond 10 PeV energy, cosmic neutrinos provide a natural beam to study neutrinos themselves.
