Seminar:- Diffuse Neutrinos and Gamma-rays from Galaxy and Cluster Mergers
The speaker reviews the recent observations of the diffuse neutrino background obtained by the IceCube Antarctic Cherenkov detector, and the data on the diffuse gamma-ray background obtained by the Fermi satellite. The process of large scale structure formation in the Universe involves continued mergers of galaxies and clusters of galaxies, resulting in shocks where particle acceleration can lead to both neutrinos and gammas, and the speaker discusses how these can contribute a significant fraction of the observed backgrounds.
