Title: Probing the Black Hole–Jet Connection

Abstract: Supermassive black holes power relativistic jets via the Blandford–Znajek (BZ) mechanism, in which magnetic fields siphon spin energy away from the hole and convert it into Poynting flux. “Horizon-scale” black hole observations now enable direct investigation of the BZ mechanism, and the next generation of experiment will facilitate a detailed comparison between theory and data. I will discuss how theoretical modeling and numerical simulations can inform quantitative observational probes of the BZ mechanism through considering the dynamics and entrainment of plasma in the ergoregion near the jet base and the effects of thermodynamic and other modeling uncertainties on observables. I will conclude with an overview of black hole glimmer, a robust non-degenerate time-domain signature of a black hole's mass and angular momentum vector. 

Bio: George N. Wong is a member of the Institute for Advanced Study and an Associate Research Scholar at the Princeton Gravity Initiative. He studies high energy astrophysical processes, especially in the context of observational signatures of black hole accretion. He received his Ph.D. in 2021 from the University of Illinois at Urbana–Champaign.
