Quasinormal modes and shadow of Schwarzschild-Tangherlini black hole with GUP

J. A. V. Campos, M. A. Anacleto, F. A. Brito +2

In this work, we investigate quasinormal modes and the shadow of a Schwarzschild-Tangherlini black hole in dimensions, incorporating corrections arising from the Generalize…

Absorption and quasinormal modes by rotating acoustic black holes in Lorentz-violating background

J. A. V. Campos, M. A. Anacleto, F. A. Brito +2

In this work, we investigate the effects of Lorentz symmetry violation on the absorption cross section and quasinormal modes of a rotating acoustic black hole in (2+1) dimensions,…

The dark sector of the Universe as a scalar field in Horndeski Gravity

M. S. Oliveira, F. A. Brito, J. A. V. Campos

In the present work, we study a subclass of Horndeski gravity characterized by a non-minimal derivative coupling between a scalar field and the Einstein tensor, as a possible alter…

Intermediate Coupling Regime in Dilatonic Inflationary Universe

Francisco A. Brito, Carlos H. A. B. Borges, Jose A. V. Campos +1

In the present work we study cosmology in dilatonic gravity to address the inflationary phase of the early Universe. As usual, in dilatonic gravity the scalar potential as…

Hunting for extra dimensions in black hole shadows

A. S. Lemos, J. A. V. Campos, F. A. Brito

Observational data of the Sagittarius A* (Sgr A*) shadow released by the Event Horizon Telescope (EHT) are used to investigate eventual deviations in the black hole shadow radius,…

Oscillating soliton stars with network of domain walls

Stephen Owusu, Jose A. V. Campos, Francisco A. Brito

In this work we study oscillating soliton stars (oscillatons) with network of domain walls. We consider a Lagrangian with three scalar fields coupled among themselves by a specific…
