Rotating regular black holes in conformal massive gravity

Understand

In this paper, we use a suitable conformal rescaling to construct static and rotating regular black holes in conformal massive gravity.

• The new metric is characterized by the mass $M$, the "scalar charge" $Q$, the angular momentum parameter $a$, the "hair parameter" $\lambda$, and the conformal scale factor encoded in the parameter $L$.
• We explore the shadow images and the deflection angles of relativistic massive particles in the spacetime geometry of a rotating regular black hole.
• For $\lambda \neq 0$ and $Q > 0$, the shadow is larger than the shadow of a Kerr black hole.
