Bouncing cosmological model with general relativistic hydrodynamics in extended gravity

A. Y. Shaikh, Sankarsan Tarai, S. K. Tripathy +1

In this paper, in an extended theory of gravity, we have presented bouncing cosmological model at the backdrop of an isotropic, homogeneous space-time, in presence of general relat…

Cosmological models with Big rip and Pseudo rip Scenarios in extended theory of gravity

Pratik P. Ray, Sankarsan Tarai, B. Mishra +1

In this paper, we have presented the big rip and pseudo rip cosmological models in an extended theory of gravity. The matter field is considered to be that of perfect fluid. The ge…

Effect of bulk viscosity in cosmic acceleration

Sankarsan Tarai, Pratik P Ray, B. Mishra +1

In this paper, we have investigated the late time cosmic acceleration issue in the context of gravity. The matter field is considered to be that of viscous fluid. The mode…

Vacuum energy and Primordial Black Holes in Brans-Dicke Theory

Debabrata Dwivedee, Bibekananda Nayak, Lambodar Prasad Singh

In our work, we study the evolution of primordial black holes within the context of Brans-Dicke theory by assuming present universe as vacuum dominated. We also consider the accret…

Accretion of radiation and rotating Primordial black holes

Swapna Mahapatra, Bibekananda Nayak

We consider rotating Primordial black holes (PBHs) and study the effect of accretion of radiation in the radiation dominated era. The central part of our analysis deals with the ro…
