General relativity (GR) is a well-tested theory of gravity in strong and weak field regimes.
Many modifications to this theory were obtained, including different scalar, vector, and tensor …

Understanding the nature of dark energy in the universe is an actual issue in theoretical
astrophysics and cosmology. One way to do it is by probing dark fluids with different …

Abstract Analysis of test magnetized and charged particles around black holes immersed in
external magnetic fields may help to explain the observed astrophysical phenomena related …

In the present work, we first regularize a black hole spacetime in modified gravity (MOG) in
the presence of the scalar-tensor-vector (STV) field, called the Schwarzschild MOG black …

Quasiperiodic oscillations (QPOs) are a powerful tool for testing gravity theories, probing
gravitational and electromagnetic field properties, and obtaining constraints on the black …

We investigate in detail the weak-field gravitational lensing of a relativistic neutral massive
particle induced by a regular black-bounce-Schwarzschild black hole proposed by Simpson …

Using the Israel-Darmois junction conditions, we obtain a class of regular dynamical
interiors to the recently proposed black-bounce spacetimes which regularises the …

The topology of equatorial time-like circular orbits around quiescent black holes is a subject
of significant interest in the realms of quantum mechanics and gravitational physics …
