Enrico Peretti | Particle acceleration and multi-messenger radiation from astrophysical outflows

Friday 3 Mar 2023, 10:30 → 12:00 Europe/Berlin

SR 05 (Villa + Zoom)

Winds and outflows are ubiquitous at several scales throughout the Cosmos. 
They often develop a bubble structure characterized by strong shocks and turbulence where high-energy particles can be efficiently produced. 
 

I will present a model in which diffusive shock acceleration is a key process to energize particles in such astrophysical winds.

I will show some model applications in the context of young massive stellar clusters, starburst galaxies and active galactic nuclei and 
I will discuss the associated multi-messenger implications in terms of high-energy photons, neutrinos and escaping cosmic rays.
