First results of low-energy neutrino follow-ups of Run O4 compact binary mergers with the IceCube Neutrino Observatory

First results of low-energy neutrino follow-ups of Run O4 compact binary mergers with the IceCube Neutrino Observatory

We present the results of searches for astrophysical neutrinos of few GeV energy from compact binary mergers detected during the first months of the fourth observing run of the LIGO, Virgo, and KAGRA interferometers. We describe our method, based on a selection of 0.5 − 5 GeV neutrino events in …
