Constraints on multi-fluid cosmology in modified Gauss-Bonnet gravity models with different observational data sets
Praveen Kumar Dhankar, Albert Munyeshyaka, Aritra Sanyal +2
In the present work, we incorporate redshift-space distortion measurement to investigate the growth of large scale structure within the framework of multi-fluid cosmology in the co…
Cosmic Hysteresis in Reconstructed Bounce Models: A Thermodynamic Study
Aritra Sanyal, Praveen Kumar Dhankar, Albert Munyeshyaka +2
We study the emergence of cosmic hysteresis in cyclic bouncing universes within the framework of analytically reconstructed gravity. Using exact bouncing scale factor soluti…
Matter power spectrum in a power-law gravity
Albert Munyeshyaka, Praveen Kumar Dhankar, Joseph Ntahompagaze
Cosmological models based on gravity are efficient in fitting different observational datasets at both background and perturbation levels. This motivates the current study t…
Large scale structure constraints and matter power spectrum in gravity
Praveen Kumar Dhankar, Albert Munyeshyaka, Saddam Hussain +1
In the present work, we take into account the dynamical system analysis to investigate the matter power spectrum within the framework of the gravitational th…
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…
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…
