Abstract

LHAASO has discovered PeVatrons in the Milky Way. The first Cosmic Ray Super-PeVatron is found in the Cygnus region with 8 photons above 1 PeV pile-up in a so-called cosmic ray bubble of 10°. A couple of PWNe are found emitting photons up to 2 PeV. They pose challenges by manifesting so-called “Extreme Accelerators” in our galaxy. In future, we need to improve the spatial resolution to carry out deep investigations for the mechanism. Detection of Neutrinos from the PeVatrons will put in the last piece of the big puzzle lasted for a century. 

Timbits, coffee, tea will be served in STI A before the colloquium.
