Astrophysical Neutrinos in the Era of Time-Domain Multimessenger Astronomy

Neutrinos are chargeless, weakly interacting cosmic messengers that carry critical information about the Universe's most violent regions. They can penetrate the dense environments surrounding supermassive black holes and travel across intergalactic distances with energies beyond the reach of Earth-based accelerators. The IceCube Neutrino Observatory, located at the South Pole, has made groundbreaking discoveries in searches for both steady and transient astrophysical sources. In this talk, I will provide an overview of the current state of astrophysical neutrino observations in the context of multimessenger astrophysics and highlight new initiatives aimed at enhancing time-domain follow-up capabilities in IceCube.
