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…
Accretion Flow Morphology in Numerical Simulations of Black Holes from the ngEHT Model Library: The Impact of Radiation Physics
Koushik Chatterjee, Andrew Chael, Paul Tiede +18
In the past few years, the Event Horizon Telescope (EHT) has provided the first-ever event horizon-scale images of the supermassive black holes (BHs) (M87*) and Sagittarius A (…
Measuring the Ellipticity of M 87* Images
Paul Tiede, Avery E. Broderick, Daniel C. M. Palumbo +1
The Event Horizon Telescope (EHT) images of the supermassive black hole at the center of the galaxy M 87 provided the first image of the accretion environment on horizon scales. Ge…
Bayesian Accretion Modeling: Axisymmetric Equatorial Emission in the Kerr Spacetime
Daniel C. M Palumbo, Zachary Gelles, Paul Tiede +4
The Event Horizon Telescope (EHT) has produced images of two supermassive black holes, Messier~87* (M 87*) and Sagittarius~A* (Sgr A*). The EHT collaboration used these images to i…
Multi-frequency Black Hole Imaging for the Next-Generation Event Horizon Telescope
Andrew Chael, Sara Issaoun, Dominic W. Pesce +4
The Event Horizon Telescope (EHT) has produced images of the plasma flow around the supermassive black holes in Sgr A* and M87* with a resolution comparable to the projected size o…
Unraveling Twisty Linear Polarization Morphologies in Black Hole Images
Razieh Emami, Angelo Ricarte, George N. Wong +23
We investigate general relativistic magnetohydrodynamic simulations (GRMHD) to determine the physical origin of the twisty patterns of linear polarization seen in spatially resolve…
