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 …

Non-linear electrodynamics (NLED) theories are well-motivated extensions of QED in the
strong field regime, and have long been studied in the search for regular black hole (BH) …

We develop a number of novel “black-bounce” spacetimes. These are specific regular black
holes where the area radius always remains nonzero, thereby leading to a “throat” that is …

In the framework of scalar-Einstein-Gauss-Bonnet gravity, we construct the Hayward black
hole model and discuss the absence of ghosts in this model. Because a Hayward black hole …

Black bounces are spacetimes that can describe, depending on certain parameters, black
holes or wormholes. In this work, we use a method to obtain the matter content that …

The object of this article is to study a new class of dark energy stars in the background of f
(Q) f(Q) gravity by using the metric potentials proposed by Krori‐Barua J. Phys. A, Math. Gen …

In this paper we present a Bardeen solution surrounded by a cloud of strings fluid. We show
how this model has the same event horizon characteristic as the Bardeen solution. However …

A string is the one-dimensional generalization of a point particle. In this sense, the analog of
a cloud of dust would be a cloud of strings. In this work, we consider a cloud of strings …

In this study, we explore the black bounce solution in Rastall gravity and its potential source
field, which can be described as a black hole or wormhole solution depending on certain …

We study static, spherically symmetric black holes supported by the Euler-Heisenberg theory
of electrodynamics and coupled to two different modified theories of gravity. Such theories …
