Observational analysis of bulk viscous modified Chaplygin gas in (2+1)-dimensional universe using MCMC
Praveen Kumar Dhankar, Aritra Sanyal, Albert Munyeshyaka +2
This paper investigates regarding cosmological implications of a bulk viscous modified Chaplygin gas (MCG) in (2+1)-dimensional Friedmann-Robertson-Walker spacetime, incorporating…
Joint Analysis of Constraints on f(R) Parametrization from Recent Cosmological Observations
Darshan Kumar, Praveen Kumar Dhankar, Saibal Ray +1
In this study, we present constraints on the parameters of three well-known gravity models, viz. (i) Hu-Sawicki, (ii) Starobinsky, and (iii) ArcTanh by using a joint analysi…
Perturbations with bulk viscosity in modified chaplygin gas cosmology
Albert Munyeshyaka, Praveen Kumar Dhankar, Joseph Ntahompagaze
In the present work, we investigate cosmological perturbations of viscous modified chaplygin gas model. Using 1 + 3 covariant formalism, we define covariant and gauge invariant gra…
