Exploring robust correlations between fermionic dark matter model parameters and neutron star properties: A two-fluid perspective [PDF]
Physical Review D, 2023 The current observational properties of neutron stars have not definitively ruled out the possibility of dark matter. In this study, we primarily focus on exploring correlations between the dark matter model parameters and different neutron star ...

Magnetized black holes surrounded by dark fluid in Lovelock-power-Yang-Mills gravity [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We consider a model where static spherically symmetric black hole, in the presence of power-Yang-Mills source, is surrounded by a dark fluid with a non-linear equation of state.

Thermodynamical analysis of charged rotating black hole surrounded by perfect fluid dark matter
Nuclear Physics B, 2023 This paper is devoted to studying thermodynamics and particle acceleration around charged rotating BHs surrounded by perfect fluid dark matter. In the beginning, we discuss BH horizons, ergosphere and inner stable circular orbits in the framework of ...

Analysis of the H0 tension problem in the Universe with viscous dark fluid [PDF]
, 2020 In this paper, two inhomogeneous single fluid models for the Universe, which are able to naturally solve the $H_{0}$ tension problem, are discussed. The analysis is based on a Bayesian Machine Learning approach that uses a generative process. The adopted

The Unifying Dark Fluid Model [PDF]
AIP Conference Proceedings, 2010 The standard model of cosmology relies on the existence of two components, "dark matter" and "dark energy", which dominate the expansion of the Universe. There is no direct proof of their existence, and their nature is still unknown. Many alternative models suggest other cosmological scenarios, and in particular the dark fluid model replace the dark ...

Gravitational lensing by a charged spherically symmetric black hole immersed in thin dark matter
European Physical Journal C: Particles and Fields, 2023 We investigate the gravitational lensing effect around a spherically symmetric black hole, whose metric is obtained from the Einstein field equation with electric charge and perfect-fluid dark matter contributing to its energy-momentum tensor.

Galaxies, 2023 We investigate some properties of exotic spherical configurations made of dark matter and dark energy. For the former, we adopt a polytropic equation-of-state, while for the latter, we adopt the extended Chaplygin gas equation-of-state.

Shadow and deflection angle of charged rotating black hole surrounded by perfect fluid dark matter [PDF]
Classical and quantum gravity, 2021 We analysed the shadow cast by charged rotating black hole (BH) in presence of perfect fluid dark matter (PFDM). We studied the null geodesic equations and obtained the shadow of the charged rotating BH to see the effects of PFDM parameter γ, charge Q ...
