Title: Black Hole Imaging: Past, Present, Future
Abstract: Images of black holes, like those first provided by the Event Horizon Telescope, can reveal how black holes interact with their environment and test theories of gravity. I will review early imaging results and describe what progress can be expected in the near future. Numerical models are essential to understanding black hole images. I will describe what current models predict about the asymmetry of the characteristic ring seen in Event Horizon Telescope images and how that is related to the magnitude and direction of black hole spin.
