摘要(Abstract):

The image of black hole consists of the black hole shadow and accretion construction, of which the shape and size reflect the properties of the central black hole. In this talk, I will present the constraints on the hairy black holes with the use of Event Horizon Telescope observations for supermassive M87* and SgrA* black holes. Then I will show the rings and images of a hairy black hole illuminated by various thin accretions, which differentiate the Schwarzschild black hole in general relativity.
