Mesonic tilted cosmological model with wet dark fluid in F(T) theory of gravity

Canadian journal of physics (Print), 2020
This study presents mesonic tilted cosmological models with wet dark fluid in the F(T) theory of gravity, which is an extension of the Teleparallel theory of gravity, where T is the torsion scalar.

Effect of plasma on gravitational lensing by a Schwarzschild black hole immersed in perfect fluid dark matter

Physical Review D, 2021
We have explored the effect of both uniform and nonuniform distributed plasma medium on gravitational lensing around static black hole in the presence of perfect fluid dark matter (PFDM).

Charged Lovelock black holes in the presence of dark fluid with a nonlinear equation of state

The European Physical Journal Plus, 2019
We consider a model that charged static spherically symmetric black hole is surrounded by dark fluid with nonlinear equation of state $$p_\mathrm{d}=-B/\rho _\mathrm{d}$$ p d = - B / ρ d .

Shadow of rotating black holes surrounded by dark fluid with Chaplygin-like equation of state and constraints from EHT results

Classical and quantum gravity
In this work, we mainly focus on testing the spacetime properties around black holes surrounded by a dark fluid, which are potential candidates for dark energy described by the Chaplygin-like equation of state through its shadow.

Universe with wet dark fluid: A dynamical systems approach

International Journal of Geometric Methods in Modern Physics (IJGMMP), 2019
We investigate the dynamical systems analysis of Friedmann–Robertson–Walker (FRW) cosmological model with wet dark fluid. A new equation of state for the dark energy component of the Universe has been used. It is modeled by the equation of state [Formula:

Instability in interacting dark energy and dark matter fluids

Nuclear Physics B - Proceedings Supplements, 2009
We consider a model of dark energy interacting with dark matter. An interaction may be interesting for the solution of the coincidence problem. We model dark energy as a fluid with constant equation of state parameter w and study background and linear perturbations. While non-interacting models with constant w are well behaved, a simple interaction

Dark Rooms and Developing Fluid

2020
Abstract Chapter 3 explores the practices of photography clubs. Throughout Ireland, during the twentieth century, men and women spent their evenings in the dark rooms of photography clubs, and their weekends on days out to historic sites and beauty spots organized by these groups.

Bianchi type VI1 cosmological model with wet dark fluid in scale invariant theory of gravitation

, 2014
In this paper, we have investigated Bianchi type VIh, II and III cosmological model with wet dark fluid in scale invariant theory of gravity, where the matter field is in the form of perfect fluid and with a time dependent gauge function (Dirac gauge). A
