Shadows of accelerating black holes
Ming Zhang, Jie Jiang
Abstract
Due to the acceleration of the black hole, circular orbits with a fixed radial coordinate and fixed latitude coordinate for photons will deviate from the equatorial plane, and the property of the black hole shadow will change. We find that the latitude of the circular orbit increases with the increasing acceleration and then show that the observer's inclination angles, which make the shadow radius and the shadow distortion a maximum, increase with the increasing acceleration for the accelerating Kerr black hole.
