Navarro-Frenk-White dark matter profile and the dark halos around disk systems
Razieh Dehghani, Paolo Salucci, H. Ghaffarnejad
The cold dark matter (CDM) scenario well describes the Universe at large scales, but shows some serious difficulties at small scales: the inner dark matter (DM) density prof…
Galaxy rotation curves and preferred reference frame effects
Hossein Ghaffarnejad, Razieh Dehghani
As an alternative to dark matter models we use generalized Jordan-Brans-Dicke scalar-vector-tensor (JBD-SVT) gravity model to study the behavior of the rotational velocities of tes…
Thermodynamical study of FRW universe in Quasi-Topological Theory
H. Moradpour, R. Dehghani
By applying the unified first law of thermodynamics on the apparent horizon of FRW universe, we get the entropy relation for the apparent horizon in quasi-topological gravity theor…
Horizon Thermodynamics and Gravitational Field Equations in Quasi-Topological Gravity
A. Sheykhi, M. H. Dehghani, R. Dehghani
In this paper we show that the gravitational field equations of % -dimensional topological black holes with constant horizon curvature, in cubic and quartic quasi-topologica…
Thermodynamics of Quasi-Topological Cosmology
M. H. Dehghani, A. Sheykhi, R. Dehghani
In this paper, we study thermodynamical properties of the apparent horizon in a universe governed by quasi-topological gravity. Our aim is twofold. First, by using the variational…
