Sasha Philippov, Ph.D.Associate Research Scientist, Compact Objects, CCA, Flatiron Institute
Simons Foundation Presidential Lectures are free public colloquia centered on four main themes: Biology, Physics, Mathematics and Computer Science, and Neuroscience and Autism Science. These curated, high-level scientific talks feature leading scientists and mathematicians and are intended to foster discourse and drive discovery among the broader NYC-area research community. We invite researchers in the area — as well as interested members of the metropolitan public — to join us for this weekly lecture series.
Supermassive black holes in some active galaxies’ centers create powerful jets of radiation and plasma particles that move close to the speed of light. The answers to the questions “how exactly are jets powered by energy extraction from a black hole” and “what are the processes that energize plasma particles” are crucial to understanding the observed activity. Recent years opened new spectacular observational windows into studying plasmas that emit observed light, including multi-wavelength observations of powerful flares and the black hole “shadow” by the Event Horizon Telescope. These exciting discoveries, as well as attempts to improve the understanding of the nature of the curved spacetime, call for a new level of quantitative understanding of plasma dynamics around black holes.
In this lecture, Sasha Philippov will discuss recent progress in first-principles numerical modeling of exciting plasma physics processes that can power jets, flares and lightning from black holes.
Registration is required for this free event.
