Description
High-energy neutrinos are believed to be produced in cosmic accelerators as a result of hadronic interactions. Cores of active galactic nuclei are considered to be among the primary sites for cosmic-ray acceleration and neutrino production. The latter is facilitated by the dense matter and radiation in the vicinity of the supermassive black holes. The recent observation by the IceCube Neutrino Observatory of NGC 1068 and the identification of similar candidate sources have reinforced the idea that neutrinos are produced in dense cores that are opaque to very-high-energy gamma rays. In this poster, we present the IceCube search for neutrino emission from Compton-thick AGN using the combined, multi-flavor IceCube event sample. We will discuss both individual-source and stacking analyses using a generic power-law neutrino spectrum and a physically motivated disk-corona emission model.
