Very compact objects probe extreme gravitational fields and may be the key to understand
outstanding puzzles in fundamental physics. These include the nature of dark matter, the …

Motivated by recent work on the Modified Maxwell (ModMax) black holes [Phys Lett B
10.1016/j. physletb. 2020.136011], which are invariant in duality rotations and conformal …

Recently, a novel 4D Einstein–Gauss–Bonnet gravity was formulated by Glavan and Lin
(Phys Rev Lett 124 (8): 081301, 2020). Although whether the theory is well defined is …

Recently a D-dimensional regularization approach leading to the non-trivial (3+ 1)(3+ 1)-
dimensional Einstein–Gauss–Bonnet (EGB) effective description of gravity was formulated …

In the present paper, we investigate the thermodynamics of a new perturbed black hole
solution in symmetric teleparallel gravity. Our main focus is on the solution for a nonlinear …

It is commonly believed that the ringdown signal from a binary coalescence provides a
conclusive proof for the formation of an event horizon after the merger. This expectation is …

Macroscopic objects, as we see them all around us, are governed by a variety of forces,
derived from a variety of approximations to a variety of physical theories. In contrast, the only …

We introduce a family of solutions of Einstein's gravity minimally coupled to an anisotropic
fluid, describing asymptotically flat black holes with “hair” and a regular horizon. These …

The existence of black holes and spacetime singularities is a fundamental issue in science.
Despite this, observations supporting their existence are scarce, and their interpretation is …
