The 2nd LHAASO Symposium

"The detection of extended multi-TeV gamma ray halos around pulsars provides a unique tool to investigate the propagation of cosmic rays in the magnetized turbulent interstellar medium around sources.
Such emission has been analyzed in the framework of isotropic diffusion, invariably leading to infer a diffusion coefficient in the source region two-three orders of magnitude smaller than that...

"Observations by HESS have indicated that the center of the galaxy harbors a hadronic
Pevatron accelerator. The subsequent propagation of these PeV particles accelerated are considered
in the framework of a Galactic center driven outflow. Non-thermal signatures from this outflow are
discussed."
