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…

Probing plasma composition with the next generation Event Horizon Telescope (ngEHT)

Razieh Emami, Richard Anantua, Angelo Ricarte +15

We explore the plasma matter content in the innermost accretion disk/jet in M87* as relevant for an enthusiastic search for the signatures of anti-matter in the next generation of…

Emission Modeling in the EHT-ngEHT Age

Richard Anantua, Joaquín Dúran, Nathan Ngata +9

This work proposes a methodology to test phenomenologically-motivated emission processes that account for the flux and polarization distribution and global structure of the 230 GHz…

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…

Resolving the inner parsec of the blazar J1924-2914 with the Event Horizon Telescope

Sara Issaoun, Maciek Wielgus, Svetlana Jorstad +27

The blazar J1924-2914 is a primary Event Horizon Telescope (EHT) calibrator for the Galactic Center's black hole Sagittarius A*. Here we present the first total and linearly polari…

Effects of Hydrogen vs. Helium on Electromagnetic Black Hole Observables

George N. Wong, Charles F. Gammie

The centers of our galaxy and the nearby Messier 87 are known to contain supermassive black holes, which support accretion flows that radiate across the electromagnetic spectrum. A…
