Linear cosmological perturbations in Scalar-tensor-vector gravity
Sara Jamali, Mahmood Roshan, Luca Amendola
We investigate the cosmological perturbations in the context of a Scalar-Tensor-Vector theory of Gravity known as MOG in the literature. Recent investigations show that MOG reprodu…
Post-Newtonian corrections to Toomre's criterion
Ali Kazemi, Mahmood Roshan, Elham Nazari
The gravitational stability of a two-dimensional self-gravitating and differentially rotating gaseous disk in the context of post-Newtonian (hereafter PN) theory is studied. Using…
Local fragmentation of thin disks in Eddington-inspired gravity
Mahmood Roshan, Ali Kazemi, Ivan De Martino
We find the generalized version of the Toomre's criterion for the stability of a rotating thin disk in the context of Eddington inspired Born-Infeld (EiBI) gravity which possesses…
Post-Newtonian magnetohydrodynamics
Elham Nazari, Mahmood Roshan
In this paper, we derive the post-Newtonian equations of the ideal Magnetohydrodynamics. To do so, we use the modern approach to post-Newtonian theory, where the harmonic gauge is…
Compact stars in Energy-Momentum Squared Gravity
Nasrin Nari, Mahmood Roshan
A simple generalization to Einstein's general relativity (GR) was recently proposed which allows a correction term in the action functional of the theory. This theor…
Stellar Bar evolution in the absence of dark matter halo
Mahmood Roshan
We study the stellar bar growth in high resolution numerical galaxy models with and without dark matter halos. In all models the galactic disk is exponential and the halos are rigi…
