SUMMARY:The Black Hole Diet: How Accretion Controls Spin\, Growth\, an
 d Feedback\, Physics Department Colloquium\, Alexander Tchekhovskoy\, 
 Northwestern University
DESCRIPTION:A black hole’s accretion rate controls its destiny\, gov
 erning its spin\, growth\, luminosity\, and feedback. However\, connec
 ting these crucial quantities to the scales that we can actually obser
 ve remains a major theoretical hurdle. In this talk\, I will present r
 ecent simulations of magnetized gas feeding rapidly rotating black hol
 es. These models offer new insights into the mechanics of gas consumpt
 ion and ejection. I will demonstrate how these findings apply to a vas
 t range of systems\, linking the physics of supermassive black holes a
 t the centers of galaxies to stellar-mass black holes born in dying st
 ars.
