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…

3D MHD Simulation of a Pulsationally-Driven MRI Decretion Disc

Sean M. Ressler

We explore the pulsationally driven orbital mass ejection mechanism for Be star disc formation using isothermal, 3D magnetohydrodynamic (MHD) and hydrodynamic simulations. Non-radi…

Relative depolarization of the black hole photon ring in GRMHD models of Sgr A* and M87*

A. Jiménez-Rosales, J. Dexter, S. M. Ressler +15

Using general relativistic magnetohydrodynamic simulations of accreting black holes, we show that a suitable subtraction of the linear polarization per pixel from total intensity i…

Magnetically Modified Spherical Accretion in GRMHD: Reconnection-Driven Convection and Jet Propagation

Sean M. Ressler, Eliot Quataert, Christopher J. White +1

We present 3D general relativistic magnetohydrodynamic(GRMHD) simulations of zero angular momentum accretion around a rapidly rotating black hole, modified by the presence of initi…

Ab Initio Horizon-Scale Simulations of Magnetically Arrested Accretion in Sagittarius A* Fed by Stellar Winds

Sean M. Ressler, Christopher J. White, Eliot Quataert +1

We present 3D general relativistic magnetohydrodynamic (GRMHD) simulations of the accretion flow surrounding Sagittarius A* that are initialized using larger-scale MHD simulations…

Sgr A* near-infrared flares from reconnection events in a magnetically arrested disc

J. Dexter, A. Tchekhovskoy, A. Jiménez-Rosales +14

Large-amplitude Sgr A* near-infrared flares result from energy injection into electrons near the black hole event horizon. Astrometry data show continuous rotation of the emission…
