  • In the framework of the concordance cosmological model the first-order scalar and vector perturbations of the homogeneous background are derived without any supple- mentary approximations in addition to the weak gravitational field limit. The sources of these perturbations (inhomogeneities) are presented in the discrete form of a system of sep- arate point-like gravitating masses. The obtained expressions for the metric corrections are valid at all (sub-horizon and super-horizon) scales and… CONTINUE READING
