Newton gauge cosmological perturbations for static spherically symmetric modifications of the de Sitter metric
ABSTRACT: Static coordinates can be convenient to solve the vacuum Einstein’s equations in presence of spherical symmetry, but for cosmological applications comoving coordinates are more suitable to describe an expanding Universe, especially in the framework of cosmological perturbation theory (CPT)...
