Abstract:
Astrophysical plasmas are extraordinary pa rticle accelerators\, from supernova remnants to the relativistic jets tha t emanate from supermassive black holes and produce very-high-energy cosmi c rays and shine across the electromagnetic spectrum. The mechanisms behin d these cosmic accelerators remain a long-standing mystery. They are thoug ht to be associated with basic plasma processes\, including collisionless shocks and magnetic reconnection\, that control energy dissipation in thes e systems. These processes involve a complex and nonlinear interplay betwe en the dynamics of flows\, magnetic fields\, and nonthermal particles that is not yet well understood and affects the observational manifestations o f the astrophysical environments. I will discuss how the fast progress in computational and experimental capabilities is creating unique opportuniti es to push the boundaries of our understanding of the dominant particle ac celeration mechanisms by allowing detailed kinetic modeling of different p lasma processes and controlled laboratory experiments that can help valida te these models.
