Description
Core-collapse supernovae are of particular interest in multi-messenger astronomy due to their potential to accelerate cosmic rays and produce high-energy neutrinos. One such supernova is the recent SN2023ixf located in M101 (the Pinwheel Galaxy). It is the closest (6.4 Mpc) and brightest (B band magnitude 10.8) core-collapse supernova in nearly a decade. This supernova likely had a progenitor surrounded by dense circumstellar material, which during the supernova may have produced neutrinos when ejecta collided with the material. I will present results of a follow up of this supernova using data collected from the IceCube Neutrino Observatory located at the South Pole. We obtain results consistent with background expectations, with time-integrated energy flux (E^2 dN/dE) upper limits of 0.35 GeV/cm^2 for a 32-day time window and 0.44 GeV/cm^2 for a 4-day time window, both at 90% confidence level for an E^-2 power law. These correspond to values of 2.7e48 erg for the 32-day time window and 3.5e48 erg for the 4-day time window at the supernova.
