Magnetic Flux Transport in Radiatively Inefficient Accretion Flows and the Pathway towards a Magnetically Arrested Disk
Prasun Dhang, Xue-Ning Bai, Christopher J. White
Large-scale magnetic fields play a vital role in determining the angular momentum transport and generating jets/outflows in the accreting systems, yet their origin remains poorly u…
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…
Blacklight: A General-Relativistic Ray-Tracing and Analysis Tool
Christopher J. White
We describe the Blacklight code, intended for post-processing general-relativistic magnetohydrodynamic simulation data. Beyond polarized ray tracing of synchrotron radiation, it ca…
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…
