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…
Remarkable correspondence of Sagittarius A* submillimeter variability with a stellar-wind-fed accretion flow model
Lena Murchikova, Christopher J. White, Sean M. Ressler
We compare the 230 GHz near-horizon emission from Sagittarius A* to simulations representing three classes of accretion flows. Using the structure function to capture the variabili…
Observational Signatures of Black Hole Accretion: Rotating vs. Spherical Flows with Tilted Magnetic Fields
He Jia, Christopher J. White, Eliot Quataert +1
We study the observational signatures of magnetically arrested black hole accretion with non-rotating inflow onto a rotating black hole; we consider a range of angles between the b…
