Physics Department Colloquium
Particle acceleration and magnetic field generation in astrophysical plasmas
Date: Friday, October 16th
Time: 3:30 pm
Place: 2241 Chamberlin Hall (Coffee & Cookies at 3:15pm)
Speaker: Anatoly Spitkovsky, Princeton University
Abstract: Shocks in low density plasmas (so-called "collisionless shocks") are ubiquitous throughout the Universe, and are thought to be responsible for the generation of nonthermal particles that extend over decades in energy. I will describe the progress in modeling collisionless shock structure and particle acceleration using ab-initio kinetic simulations, focusing on the current understanding of magnetic field amplification mechanisms, the conditions necessary for particle injection into the acceleration process, and the physics behind the electron-to-ion ratio in shock acceleration. I will also describe a new scenario for generation of the first magnetic fields during structure formation that can be important for seeding magnetic fields in galaxies.
