Shadow of a Kerr-like black hole

摘要

The shadow of a Kerr-like black hole has been considered and it was shown that in addition to the specific angular momentum a, deformation parameter of Kerr-like space-time essentially deforms the shape of the black hole shadow. For a given value of the black hole spin parameter a, the presence of a deformation parameter ? reduces the shadow and enlarges its deformation with respect to the one in the Kerr space-time.
