Searches for neutrino emission from GRB 221009A with the IceCube Neutrino Observatory

Gamma-ray bursts are a promising source of hadronic acceleration and have been the target of many neutrino searches. However, thus far no significant detection of neutrinos from a GRB has been observed. The detection of the brightest GRB ever observed, GRB 221009A, provides a unique opportunity for investigation of GRBs as neutrino sources. GRB 221009A provides the strongest constraints ever on neutrino emission from a single GRB due to its high luminosity, low redshift, and advantageous declination for follow-up with the IceCube Neutrino Observatory. In this talk, we will discuss results of both realtime and offline neutrino searches from GRB 221009A with IceCube across a wide range of timescales and from MeV to PeV energies.
