The Lorentz symmetry of gravity is spontaneously broken when the nonminimally coupled
Kalb-Ramond field acquires a nonzero vacuum expectation value. In this work, we present …

A general covariant Einstein–Gauss–Bonnet Gravity in Four-Dimensional (4D EGB)
spacetime is shown to bypass Lovelock's theorem and is free from Ostrogradsky instability …

Recently, a static spherically symmetric black hole solution was found in gravity
nonminimally coupled a background Kalb-Ramond field. The Lorentz symmetry is …

Motivated by a new model of nonlinear electrodynamics known as Modified Maxwell
(ModMax) theory, an exact analytical solution for black holes is obtained by coupling …

This study explores the impact of antisymmetric tensor effects on spherically symmetric black
holes, investigating photon spheres, shadows, emission rate and quasinormal frequencies …

We derive the exact solutions for electrically charged black holes both in the absence and
presence of a cosmological constant in the gravitational theory with Lorentz violation …

In this study, we investigate the quasinormal modes (QNMs) of a Lorentz-violating
spacetime, factoring in a cosmological constant, within the framework of Einstein-bumblebee …

Real astronomical objects possess spin, yet deriving exact solutions for rotating black holes
within gravitational theories is a formidable challenge. To understand the shadow of rotating …

Spherical black hole (BH) solutions have been found in the bumblebee gravity where a
vector field nonminimally couples to the Ricci tensor. We study dynamic (in) stability …

We derive the exact solutions for electrically charged black holes both in the absence and
presence of a cosmological constant in the gravity theory with Lorentz violation induced by a …
