Observational constraints on Modified Chaplygin Gas from Large Scale Structure
Bikash Chandra Paul, Prasenjit Thakur, Aroonkumar Beesham
We study cosmological models with modified Chaplygin gas (in short, MCG) to determine observational constraints on its EoS parameters. The observational data of the background and…
An Emergent Universe supported by chiral cosmological fields in Einstein--Gauss--Bonnet gravity
Sergey V. Chervon, Sunil D. Maharaj, Aroonkumar Beesham ans Aleksandr Kubasov
We propose the application of the chiral cosmological model (CCM) for the Einstein--Gauss--Bonnet (EGB) theory of gravitation with the aim of finding new models of the Emergent Uni…
Nonlinear bulk viscosity and the stability of accelerated expansion in FRW spacetime
G. Acquaviva, A. Beesham
In the context of dark energy solutions, we consider a Friedmann-Robertson-Walker spacetime filled with a non-interacting mixture of dust and a viscous fluid, whose bulk viscosity…
