The Scattering and Intrinsic Structure of Sagittarius A* at Radio Wavelengths
Abstract Radio images of the Galactic Center supermassive black hole, Sagittarius A* (Sgr A*), are dominated by interstellar scattering. Previous studies of Sgr A* have adopted an anisotropic Gaussian model for both the intrinsic source and the scattering, and they have extrapolated the scattering using a purely λ 2 scaling …
