Effects of Cosmological Constant on Clustering of Galaxies
Mir Hameeda, Sudhaker Upadhyay, Mir Faizal +1
In this paper, we analyse the effect of the expansion of the universe on the clustering of galaxies. We evaluate the configurational integral for interacting system of galaxies in…
Cosmological expansion and contraction from Pauli exclusion principle in -branes
Alireza Sepehri, Ahmed Farag Ali, Kazuharu Bamba +5
We show that the Pauli exclusion principle in a system of -branes can give rise to the expansion and contraction of the universe which is located on an -brane. We start wit…
Non-singular and Cyclic Universe from the Modified GUP
Maha Salah, Fayçal Hammad, Mir Faizal +1
In this paper, we investigate the effects of a new version of the generalized uncertainty principle (modified GUP) on the dynamics of the Universe. As the modified GUP will modify…
Vaidya Spacetime for Galileon Gravity's Rainbow
Prabir Rudra, Mir Faizal, Ahmed Farag Ali
In this paper, we analyze Vaidya spacetime with an energy dependent metric in Galileon gravity's rainbow. This will be done using the rainbow functions which are motivated from the…
Stringent theoretical and experimental bounds on graviton mass
Ahmed Farag Ali, Saurya Das
We show from theoretical considerations, that if the graviton is massive, its mass is constrained to be about . This estimate is consistent with those obtained fro…
Emergence and oscillation of cosmic space by joining M1-branes
Alireza Sepehri, Farook Rahaman, Salvatore Capozziello +2
Recently, it has been proposed by Padmanabhan that the difference between the number of degrees of freedom on the boundary surface and the number of degrees of freedom in a bulk re…
