Dark Energy and Modified Scale Covariant Theory of Gravitation
Koijam Manihar Singh, Sanjay Mandal, Longjam Parbati Devi +1
Taking up four model universes we study the behaviour and contribution of dark energy to the accelerated expansion of the universe, in the modified scale covariant theory of gravit…
Wormhole model with a hybrid shape function in f(R,T) gravity
Parbati Sahoo, Sanjay Mandal, P. K. Sahoo
In the present article we propose a new hybrid shape function for wormhole (WH)s in the modified gravity. The proposed shape function satisfied the conditions of WH geomet…
Revisiting The Coincidence Problem in Gravitation
P. K. Sahoo, S. Bhattacharjee
The energy densities of dark matter (DM) and dark energy (DE) are of the same order at the present epoch despite the fact that both these quantities have contrasting characteristic…
Gravitational Baryogenesis in Non-Minimal Coupled Gravity
P. K. Sahoo, Snehasish Bhattacharjee
Baryogenesis refers to the theoretical process that occurred in the early history of the universe producing excess of matter over antimatter. Hitherto, fundamental physics which ca…
Bouncing scenario in gravity
Parbati Sahoo, S. Bhattacharjee, S. K. Tripathy +1
The present manuscript presents modeling of matter bounce in the framework of gravity where . We start by defining a parametrization of scale factor whi…
Phantom fluid wormhole in gravity
Parbati Sahoo, Annika Kirschner, P. K. Sahoo
Wormholes (WHs) are considered as hypothetical shortcuts or tunnels in spacetime. In general relativity (GR), the fundamental ingredient of WH geometry is the presence of exotic ma…
