Black holes in higher-derivative Weyl conformal gravity
Leandro A. Lessa, Caio F. B. Macedo, Manoel M. Ferreira
We obtain exact black hole solutions for static and spherically symmetric sources in a Weyl conformal gauge theory of gravity. We consider a quadratic gravitational action built fr…

Scattering effects of bumblebee gravity in metric affine formalism
N. Heidari, Caio F. B. Macedo, A. A. Araújo Filho +1
In this work, we explore a Schwarzschild-like black hole within the framework of metric--affine bumblebee gravity. First, we investigate the behavior of the Kretschmann scalar and…
