Generalized Energy-Momentum-Squared Gravity in the Palatini Formalism
Elham Nazari, Farahnaz Sarvi, Mahmood Roshan
We study the generalized version of energy-momentum squared gravity (EMSG) in the Palatini formalism. This theory allows the existence of a scalar constructed with energy-momentum…
Does modified gravity predict fast stellar bars in spiral galaxies?
Neda Ghafourian, Mahmood Roshan, Shahram Abbassi
The evolution of disk galaxies in modified gravity is studied by using high-resolution N-body simulations. More specifically, we use the weak field limit of two modified gravity th…
Jeans analysis in energy-momentum-squared gravity
Ali Kazemi, Mahmood Roshan, Ivan De Martino +1
In this paper, we study the Jeans analysis in the context of energy-momentum-squared gravity (EMSG). More specifically we find the new Jeans mass for non-rotating infinite mediums…
Gravitational radiation by magnetic field: application to millisecond magnetars
Elham Nazari, Mahmood Roshan
We investigate the direct contribution of the magnetic field to the gravitational wave generation. To do so, we study the post-Newtonian energy-momentum tensor of the magnetized fl…
