The problem of escape: a missing bit in the theory of the origin of cosmic rays
P. Blasi, E. Amato
The escape of cosmic rays from their sources, as well as from the region surrounding a source, or from the galaxy hosting the sources, is a non-linear process that involves a compl…

Suppressed diffusion and gamma-ray emission from the Cygnus bubble
Ben Li, Pasquale Blasi, Elena Amato
Recent gamma-ray observations indicate that star clusters can be efficient particle accelerators. In particular, LHAASO has detected diffuse gamma-ray emission from Cygnus OB2 exte…

Particle acceleration at recollimation shocks in sub-relativistic jets A model for jets in Seyfert Galaxies, Microquasars and Protostellar Systems
Enrico Peretti, Elena Amato, Silvio Sergio Cerri +3
Context: Growing observational evidence suggests that sub-relativistic astrophysical jets may accelerate particles at slowly evolving standing shocks. Recollimation shocks are expe…
