A bstract A bouncing scenario of a flat homogeneous and isotropic universe is explored by
using the reconstruction technique for the power-law parametrization of the Hubble …

In this paper, we consider a theory of gravity with a metric-dependent torsion namely the F
(R, T) gravity, where R is the curvature scalar and T is the torsion scalar. We study the …

In this paper, we investigate the Noether symmetries of F (T) cosmology involving matter and
dark energy. In this model, the dark energy is represented by a canonical scalar field with a …

Here, we study the effect of strong gravitational field on the light rays emitted from the
particles in the accretion disk in the vicinity of the Kerr–Newman–NUT–Kiselev (KNNK) …

In this paper, we investigate the energy conditions (including null, weak, strong, dominant) in
generalized teleparallel gravities including pure F (T), teleparallel gravity with non-minimally …

We examine the steady-state spherically symmetric accretion of relativistic fluids, with a
polytropic equation of state, onto a higher-dimensional Schwarzschild black hole. The mass …

We study the adiabatic accretion process of ordinary baryonic gas onto spherically
symmetric black holes in Einstein-Maxwell-scalar theory, with two parameters α and β in the …

We formulate and solve the problem of spherically symmetric, steady state, adiabatic
accretion onto a Schwarzschild-like black hole obtained recently. We derive the general …

We investigate the thermodynamics and phase transition for Kiselev black hole and dilaton
black hole. Specifically we consider Reissner‐Nordström black hole surrounded by radiation …

We study the evolution of primordial black holes by considering present universe is no more
matter dominated rather vacuum energy dominated. We also consider the accretion of …
