Title : Extreme Plasma Astrophysics of Black Holes and Neutron Stars

Speaker Name: Sasha Philippov

Speaker Institution : Flatiron Intstitute

Abstract : Neutron stars and black holes are powerful sources of broad-band non-thermal electromagnetic emission, including coherent radio and high-energy radiation. The collective behavior of plasmas that produce these emission signatures is still poorly understood. In order to allow modeling emission signatures from first principles, I construct radiative kinetic plasma simulations of neutron star and black hole environments. In this talk I will describe applications of these methods to the understanding of multi-wavelength pulsar emission mechanism, including the long-standing problem of the generation of coherent radio waves. I will also highlight recent work on pair plasma discharges and flares near supermassive black holes.
