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…

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…
