Towards Understanding Black Hole Accretion and Jet Launching

Séminaire IPAG de Monika Moscibrodzka (Radboud University), jeudi 17 octobre 2019 à 11h00, IPAG seminar room

One and three millimeter Very Long Baseline Interferometry experiments are constructing the images of the plasma flows in the immediate vicinity of the supermassive black holes at the centers of Milky Way and M87 galaxies. A detailed theoretical understanding of black hole astrophysics is now very crucial to interpret these observations.

The focus of the talk is on modeling total intensity and polarimetric properties of light produced in synchrotron processes and inverse-Compton process in strong gravitational field near the black hole event horizon. This polarized component of light gives us detail constraints on the magnetic field geometry and dynamics at the event horizon, which are keys to understand the accretion and jet launching process.
