title = "Simulating VLBI images of Sgr A",
abstract = "Very Long Baseline Interferometry (VLBI) at sub-millimeter/millimeter wavelengths shows promise at resolving the silhouette of the supermassive black hole at the Galactic Center, Sagittarius A* (Sgr A *), in the near future. In order to accurately test theoretical models of Sgr A* using these observations, a direct comparison of VLBI data to numerical models must be made. We present calculated images and spectra of Sgr A* using accretion disk simulation data from general relativistic magnetohydrodynamics (GRMHD) evolutions. Synchrotron and bremsstrahlung emission models are considered in the optically thin limit, which allows us to solve the radiative transfer equations using only simulation and geodesic data in a post-processing step. We show predictions of millimeter observations at the expected angular resolution limit and the spectrum's variability.",
