Title：Particle acceleration and multi-messenger radiation from astrophysical outflows

Host：Songzhan Chen

报告摘要/Abstract:

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. scenarios.
