Physics beyond the Standard Model is required to explain astrophysical observations (dark matter) and laboratory measurements (neutrino masses). In the neutrino sector, a persistent set of anomalies observed in short-baseline neutrino experiments point towards the existence of additional neutral fermions. These anomalies span a broad range of energy scales from MeV to GeV and appear in experiments that use different neutrino sources and detectors.

Many models that explain these anomalies introduce particles that mix with the known neutrino flavors. These “nu-friends” can produce signatures in high-energy neutrino experiments, such as the IceCube Neutrino Observatory near the geographic South Pole. This talk will review the efforts to search for them in IceCube.
