Abstract The Galactic Center (GC) of the Milky Way, thanks to its proximity, allows to perform
astronomical observations that investigate physical phenomena at the edge of astrophysics …

In this work, we have studied the quasinormal modes of a black hole in a model of the type f
(Q)=∑ nan QQ 0 n in f (Q) gravity by using a recently introduced method known as Bernstein …

In this work we investigate a Schwarzschild-type black hole that is corrected by the
Generalised Uncertainty Principle (GUP) and possesses topological defects within the …

The gravitational potential of a gas of initially randomly distributed primordial black holes
(PBH) can induce a stochastic gravitational-wave (GW) background through second-order …

We have obtained the Generalized Uncertainty Principle (GUP) corrected de Sitter and anti-
de Sitter black hole solutions in bumblebee gravity with a topological defect. We have …

This paper deals with the thermodynamics, Joule‐Thomson expansion and optical
behaviour of a Reissner‐Nordström‐anti‐de Sitter black hole in Rastall gravity surrounded …

We investigate the impact of the axionic coupling parameter on the bending angle of light
and the shadow cast by slowly rotating black holes in Chern–Simons modified gravity. We …

We study the tideless traversable wormholes in the f (R) gravity metric formalism. First we
consider three shape functions of wormholes and study their viabilities and structures. The …

We derive novel black hole solutions in a modified gravity theory, namely the Hu–Sawicki
model of f (R) gravity. After obtaining the black hole solution, we study the horizon radius of …

One of the notable modifications of General Relativity (GR) is the Rastall gravity. We have
studied the quasinormal modes of black holes in Rastall gravity in presence of non-linear …
