Variability in GRMHD simulations of Sgr A: Implications for EHT closure phase observations
Lia Medeiros, Chi-kwan Chan, Feryal Özel +4
The observable quantities that carry the most information regarding the structures of the images of black holes in the interferometric observations with the Event Horizon Telescope…
Persistent Asymmetric Structure of Sagittarius A* on Event Horizon Scales
Vincent L. Fish, Michael D. Johnson, Sheperd S. Doeleman +69
The Galactic Center black hole Sagittarius A* (Sgr A*) is a prime observing target for the Event Horizon Telescope (EHT), which can resolve the 1.3 mm emission from this source on…
Bayesian techniques for comparing time-dependent GRMHD simulations to variable Event Horizon Telescope observations
Junhan Kim, Daniel P. Marrone, Chi-kwan Chan +3
The Event Horizon Telescope (EHT) is a millimeter-wavelength, very-long-baseline interferometry (VLBI) experiment that is capable of observing black holes with horizon-scale resolu…
GRMHD simulations of visibility amplitude variability for Event Horizon Telescope images of Sgr A*
Lia Medeiros, Chi-kwan Chan, Feryal Ozel +4
Synthesis imaging of the black hole in the center of the Milky Way, Sgr A*, with the Event Horizon Telescope (EHT) rests on the assumption of a stationary image. We explore the lim…
