Galaxy rotation curves and preferred reference frame effects
/ Ghaffarnejad, Hossein ; Dehghani, Razieh
As an alternative to dark matter models we use generalized Jordan–Brans–Dicke scalar–vector–tensor (JBDSVT) gravity model to study the behavior of the rotational velocities of test particles moving around galaxies. [...]

ReissnerNordström Black Holes Statistical Ensembles and FirstOrder Thermodynamic Phase Transition
/ Ghaffarnejad, Hossein ; Farsam, Mohammad
We apply Debbasch proposal to obtain mean metric of coarse graining (statistical ensemble) of quantum perturbed ReissnerNordstöm black hole $(RNBH).$ Then we seek its thermodynamic phase transition behavior. [...]

Effects of a cloud of strings on the extended phase space of Einstein–Gauss–Bonnet AdS black holes
/ Ghaffarnejad, Hossein ; Yaraie, Emad
In this paper we study the thermodynamics of Einstein–Gauss–Bonnet (EGB)AdS black holes minimally coupled to a cloud of strings in an extended phase space where the cosmological constant is treated as pressure of the black holes and its conjugate variable is the thermodynamical volume of the black holes.
