The vertical structure of galactic discs: nonlocal gravity versus dark matter
Tahere Kashfi, Mahmood Roshan
Recent isolated galactic simulations show that the morphology of galactic discs in modified gravity differs from that of the standard dark matter model. In this study, we focused o…
Reconciling the magnetic field in central disc galaxies with the dynamical mass using the cosmological simulations
Mohammad Hosseinirad, Fatemeh Tabatabaei, Mojtaba Raouf +1
The Universe is pervaded by magnetic fields in different scales, although for simplicity, they are ignored in most cosmological simulations. In this paper, we use the TNG50, which…
Gravitational instability of filamentary molecular clouds, including ambipolar diffusion
Mohammad Hosseinirad, Kazem Naficy, Shahram Abbassi +1
The gravitational instability of a filamentary molecular cloud in non-ideal magnetohydrodynamics is investigated. The filament is assumed to be in hydrostatic equilibrium. We add t…
On the gravitational stability of the Maclaurin disk
Mahmood Roshan, Shahram Abbassi, Habib G. Khosroshahi
We study the global gravitational stability of a gaseous self-gravitating Maclaurin disk in the absence of a halo. Further, we replace Newtonian gravity with the specific Modified…
The phase space analysis of modified gravity (MOG)
Sara Jamali, Mahmood Roshan
We investigate the cosmological consequences of a scalar-vector-tensor theory of gravity known as MOG. In MOG, in addition to metric tensor, there are two scalar fields and…
Energy-Momentum Squared Gravity
Mahmood Roshan, Fatimah Shojai
A new covariant generalization of Einstein's general relativity is developed which allows the existence of a term proportional to in the action functional of the the…
