Chasing Ghosts: Searching for Electromagnetic Counterparts to High-Energy Neutrinos

IceCube, the world's largest neutrino observatory, first discovered a flux of high-energy astrophysical neutrinos in 2013. This discovery launched the field of neutrino astronomy, and started the ongoing search for the possible origin of these particles.This talk will introduce the current searches for neutrino sources, and in particular electromagnetic follow-up campaigns which aim to uncover counterparts in real-time. I will highlight results from the ZTF neutrino follow-up program, which suggest that TDEs produce some of the high-energy neutrino flux. I will also outline future prospects for neutrino astronomy, and the impact of time-domain surveys which are deeper (e.g Rubin) or at complementary wavelengths (e.g WINTER at NIR wavelengths).
