Dissipative unified dark fluid model [PDF]
International Journal of Modern Physics D, 2018 We consider a unified barotropic dark fluid model with dissipation. Our fluid asymptotes between two power laws and so can interpolate between the dust and dark energy (DE) equations-of-state at early and late times.

Effective fluid description of the dark universe [PDF]
Physics Letters B, 2018 We propose an effective anisotropic fluid description for a generic infrared-modified theory of gravity. In our framework, the additional component of the acceleration, commonly attributed to dark matter, is explained as a radial pressure generated by ...

Thermodynamics and evaporation of perfect fluid dark matter black hole in phantom background [PDF]
European Physical Journal C: Particles and Fields, 2023 We present a novel interpretation of the thermodynamics of perfect fluid dark matter (PFDM) black hole based on Misner–Sharp energy and then investigate its evaporation behavior.

European Physical Journal C: Particles and FieldsIn this paper, we study the higher dimensional black holes of Lovelock gravity coupled with a conformal scalar field. The matter source of gravity is suggested to come from the Chaplygin-like dark fluid, i.e., the hybrid of a dark matter and dark energy.

Black holes surrounded by Einstein clusters as models of dark matter fluid [PDF]
European Physical Journal C: Particles and Fields, 2023 We construct a novel class of spherically symmetric and asymptotically flat black holes and naked singularities surrounded by anisotropic dark matter fluid with the equation of state (EoS) of the form $$P_t=\omega \rho $$ P t = ω ρ .

A new pressure-parametrization unified dark fluid model [PDF]
European Physical Journal C: Particles and Fields, 2017 We propose a new pressure-parametrization model to explain the accelerated expansion of the late-time Universe by considering the baryon matter and dark contents (dark matter and dark energy) as a unified dark fluid. To realize this model more physically,

Statistical and Dynamical Decoupling of the IGM from Dark Matter
Advances in Astronomy, 2011 Although the gravitational field in the universe is dominated by dark matter, cosmological observations show that the statistical properties of cosmic baryonic matter are significantly and systematically decoupled from that of the underlying dark matter.
