Optical appearance of the Kerr–Bertotti–Robinson black hole with a magnetically driven synchrotron emissivity model

Abstract We investigate the optical appearance of a Kerr–Bertotti–Robinson (Kerr-BR) black hole illuminated by a geometrically and optically thin accretion disk. Instead of using a phenomenological power-law emissivity, we adopt a magnetically driven synchrotron emissivity proxy...
