Recent measurements by the Event Horizon Telescope have improved our understanding of strong gravity near supermassive compact objects. By using the shadow size of M87*, constraints on the physical charges of various types of nonrotating or rotating black holes can be inferred, helping rule out certain types of highly charged black holes. Additionally, considering black holes with two physical and independent charges allows for the exclusion of significant regions in the parameter space for specific types of black holes.
Our understanding of strong gravity near supermassive compact objects has recently improved thanks to the measurements made by the Event Horizon Telescope (EHT). We use here the M87* shadow size to infer constraints on the physical charges of a large variety of nonrotating or rotating black holes. For example, we show that the quality of the measurements is already sufficient to rule out that M87* is a highly charged dilaton black hole. Similarly, when considering black holes with two physical and independent charges, we are able to exclude considerable regions of the space of parameters for the doubly-charged dilaton and the Sen black holes.
