Abstract

We aim to leverage the transformational science enabled by the Event Horizon Telescope (EHT) to study the physics of, and near, the black holes in a sample of galaxies covering a large parameter space in supermassive black hole mass, accretion rate, and jet power. To this end, we work on a sample of nearby galaxies whose directly measured black hole masses and distances imply that 40 micro-arcsec EHT observations will resolve the central engine at <100 Schwarzschild radius resolution. To complement the near-future EHT observations, we attempt to constrain the accretion properties of nearby active galactic nuclei by modeling the broadband spectral energy distribution using a general relativistic Monte Carlo radiative transfer code. These results will provide apriori information that is vital for an accurate ray-tracing of EHT millimeter maps of accretion flows in the future.
