Превью общелабораторного семинара 31.05.2019 г. Dmitri Semikoz (Directeur de Recherche CNRS, Paris) "Multi-messenger signatures of high energy neutrino sources".

Astrophysical neutrinos was discovered by IceCube experiment in 2013. More then 100 of such neutrinos was detected by IceCube  in last years in several detection channels including all flavours of electron, muon and tau neutrinos.  Fast construction of GVD  detector in lake Baikal  give hope to make first detection of astrophysical neutrinos in the North hemisphere already 2019-2020.

In this talk I’ll review theoretical models which attempt to describe neutrino data. I’ll argue that only combined analysis of neutrino, gamma-ray and cosmic ray data can allow to study origin of astrophysical neutrinos. Finally, I’ll show  that present data can be described with  two components, which have galactic and extragalactic origin and present several models for each of those components.
