Perturbations with bulk viscosity in modified chaplygin gas cosmology

A Munyeshyaka, PK Dhankar… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …
