Gamma-ray interactions can produce detectable neutrino signals

Supports AGN as potential sources of high-energy neutrinos

Abstract

Recent astronomical observations reveal that Active Galactic Nuclei (AGN) are sources of high-energy radiation. For example, the Fermi-LAT and Hess telescopes have detected gamma-ray emissions from the cores of several types of AGN's. Even more, the Pierre Auger observatory has found a correlation of ultra-high energy cosmic ray events with the position of Active Galactic Nuclei, such as Centaurus A. In this way, according to particle physics, a flux of high-energy neutrinos should be expected from the interactions of cosmic and gamma-rays with the ambient matter and radiation at the source. In this work, estimations of the diffuse neutrino flux from AGN's arising from interactions of the gamma radiation with the gas and dust of the sources will be presented.
