We review recent progress in massive gravity. We start by showing how different theories of
massive gravity emerge from a higher-dimensional theory of general relativity, leading to the …

Shadows and gravitational weak lensing by the Schwarzschild black hole in the string cloud
background with quintessential field - IOPscience This site uses cookies. By continuing to use …

Quintessential dark energy with density ρ ρ and pressure p is governed by an equation of
state of the form p=qρ p= ω q ρ with the quintessential parameter \omega_q∈(-1;-1/3) ω q∈ …

In this paper, we investigate circular orbits for test particles around the Schwarzschild–de
Sitter (dS) black hole surrounded by perfect fluid dark matter. We determine the region of …

We construct the light escape cones of isotropic spot sources of radiation residing in special
classes of reference frames in the Kerr–de Sitter (KdS) black hole spacetimes, namely in the …

Spherically symmetric equilibrium configurations of perfect fluid obeying a polytropic
equation of state are studied in spacetimes with a repulsive cosmological constant. The …

We present a formulation of ghost-free massive gravity with flat reference metric that exhibits
the full nonlinear constraint algebraically, in a way that can be directly implemented for …

We study behaviour of gravitational waves in the recently introduced general relativistic
polytropic spheres containing a region of trapped null geodesics extended around radius of …

Abstract Considering de Rham–Gabadadze–Tolley theory of massive gravity coupled with
(ghost free) higher curvature terms arisen from the Lovelock Lagrangian, we obtain charged …

In general relativity, greybody factor is a quantity related to the quantum nature of a black
hole. A high value of greybody factor indicates a high probability that Hawking radiation can …
