Abstract:
IceCube reported the first evidence of high-energy astrophysical neutrinos in 2013 and has detected over 100 candidate events. However, the origins of these neutrinos remain elusive. Recently, IceCube reported radio-quiet active galactic nuclei as the sources of cosmic neutrinos. In addition, several potential association between non-jetted tidal disruption events and cosmic neutrino events are reported.
In the first half of this talk, I will introduce a high-energy neutrino emission model from magnetized coronae around supermassive black holes. Our model predictions are consistent with current neutrino and gamma-ray observations. In the second half, I will discuss recent efforts to identify or constrain tidal disruption events as sources of IceCube neutrinos, using optical transient surveys and currently available data. I will also outline future prospects for identifying or constraining the role of tidal disruption events as sources of high-energy neutrinos.
