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…

On 1 + 3 covariant perturbations of the quasi-Newtonian space-time in modified Gauss-Bonnet gravity
Albert Munyeshyaka, Joseph Ntahompagaze, Tom Mutabazi +1
The consideration of a 1 + 3 covariant approach to cold dark matter universe with no shear cosmological dust model with irrotational flows is developed in the context of f (G) grav…
