First Sagittarius A* Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole in the Center of the Milky Way
The Event Horizon Telescope Collaboration
We present the first Event Horizon Telescope (EHT) observations of Sagittarius A* (Sgr A), the Galactic center source associated with a supermassive black hole. These observati…
Using Machine Learning to Link Black Hole Accretion Flows with Spatially Resolved Polarimetric Observables
Richard Qiu, Angelo Ricarte, Ramesh Narayan +3
We introduce a new library of 535,194 model images of the supermassive black holes and Event Horizon Telescope (EHT) targets Sgr A* and M87*, computed by performing general relativ…
Black Hole Magnetic Fields and Their Imprint on Circular Polarization Images
Angelo Ricarte, Richard Qiu, Ramesh Narayan
The circular polarization of black hole accretion flows can encode properties of the underlying magnetic field structure. Using general relativistic magnetohydrodynamics (GRMHD) si…
