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

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.

Galactic halos of fluid dark matter [PDF]
Physical Review D, 2003 Dwarf spiral galaxies - and in particular the prototypical DDO 154 - are known to be completely dominated by an unseen component. The putative neutralinos - so far the favored explanation for the astronomical dark matter - fail to reproduce the well measured rotation curves of those systems because these species tend to form a central cusp whose ...

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 ...

On isotropic turbulence in the dark fluid universe [PDF]
The European Physical Journal C, 2011 As first part of this work, experimental information about the decay of isotropic turbulence in ordinary hydrodynamics, u^2(t) proportional to t^{-6/5}, is used as input in FRW equations in order to investigate how an initial fraction f of turbulent kinetic energy in the cosmic fluid influences the cosmological development in the late, quintessence ...

Geodesic structure, shadow and optical appearance of black hole immersed in Chaplygin-like dark fluid [PDF]
Journal of Cosmology and Astroparticle PhysicsIn this study, we focus on a black hole immersed in a cosmological Chaplygin-like dark fluid (CDF), characterized by the equation of state p = -B/ρ and an additional parameter q influencing the energy density of the fluid.
