Non-perturbative effects of primordial curvature perturbations on the apparent value of a cosmological constant

ABSTRACT: We study effects on the luminosity distance of a local inhomogeneity seeded by primordial curva- ture perturbations of the type predicted by the inflationary scenario and constrained by the cosmic microwave background radiation. We find that a local underdensity originated from a one, two...
