Effects of inhomogeneities on apparent cosmological observables: “fake” evolving dark energy
ABSTRACT: Using the exact Lemaitre-Bondi-Tolman solution with a non-vanishing cosmological constant Λ, we investigate how the presence of a local spherically-symmetric inhomogeneity can affect apparent cosmological observables, such as the deceleration parameter or the effective equation of state of...
