Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

In this work, we present black hole solutions with a cosmological constant in bumblebee
gravity, which provides a mechanism for the Lorentz symmetry violation by assuming a …

In this paper, we have studied the particle dynamics, gravitational lensing and energy
processes around the black hole (BH) in Kalb–Ramond (KR) gravity. The motion of particles …

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 bstract The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most
notably appears in the context of string theory, but has largely been unexplored in the …

The vacuum expectation value of the non-minimally coupled Kalb–Ramond (KR) field leads
to spontaneous local Lorentz symmetry violation, and static spherically symmetric solutions …

Gravitational wave physics can probe theories that extend beyond general relativity.
Motivated by recent attention on the Kalb-Ramond field as a dark matter candidate, in this …

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

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

We obtain new black hole solutions in a Einstein–Bumblebee-scalar theory. By starting with
a Einstein–Bumblebee theory in (D+ d) dimensions, the scalar dilaton field and its …
