We discuss how to constrain new physics in the neutrino sector using multimessenger astronomical observations by IceCube Generation 2. The information from time and direction coincidence with an identifiable source is used to improve the experimental sensitivity by constraining the mean free path of neutrinos from these sources. Over the coming years, IceCube Generation 2 is expected to detect neutrinos from tens of these sources. Here, we analyze the detection of neutron stars merging with black holes or neutron stars. We estimate the sensitivity to specific phenomenological models in upcoming years, including additional neutrino interactions, neutrinophilic dark matter, and lepton-number-charged axion dark matter.
