Title: Image of the shadow and thin accretion disk in gravity with a minimally coupled scalar field
Abstract: This talk will discuss the possible observable relativistic images of a black hole and naked singularity appearing in a rotating geometry in Einstein's gravity, minimally coupled to a scalar field. Particular attention will be paid to a Kerr-like (KL) alternative to the rotating Fisher-Janis-Newman-Winicour solution. The study includes analytical and numerical calculations of equatorial circular [...]
