Scalar and vector perturbations in a universe with nonlinear perfect fluid
Ezgi Canay, Ruslan Brilenkov, Maxim Eingorn +2
We study a three-component universe filled with dust-like matter in the form of discrete inhomogeneities (e.g., galaxies) and perfect fluids characterized by linear and nonlinear e…
Scalar perturbations in cosmological models: the cosmic screening approach
Ozgur Akarsu, Ruslan Brilenkov, Maxim Eingorn +2
We investigate cosmological perturbations for nonlinear models within the cosmic screening approach. Matter is considered both in the form of a set of discrete point-like ma…
Second-order Cosmological Perturbations Engendered by Point-like Masses
Ruslan Brilenkov, Maxim Eingorn
In the CDM framework, presenting nonrelativistic matter inhomogeneities as discrete massive particles, we develop the second-order cosmological perturbation theory. Our approach…
Perfect fluids with as sources of scalar cosmological perturbations
Maxim Eingorn, Ruslan Brilenkov
We make a generalization of a self-consistent first-order perturbation scheme, being suitable for all (sub-horizon and super-horizon) scales, which has been recently constructed fo…
