Optical Signatures of Black Holes Surrounded by a Generalized Cloud of Strings

Marcos V. de S. Silva, Ednaldo L. B. Junior, Carlos F. S. Pereira +1

In this work, we investigate the optical signatures of black holes surrounded by a generalized cloud of strings, described by the Letelier--Alencar spacetime. We first analyze null…

Three dimensional black bounces in $f (R)$ gravity

Marcos V. de S. Silva, Manuel E. Rodrigues, C. F. S. Pereira

We investigate the existence of black bounce solutions in $2 + 1$ dimensions within the framework of $f (R)$ gravity. We analyze whether black bounce geometries originally obtained in…
