Corrections to the apparent value of the cosmological constant due to local inhomogeneities
ABSTRACT: Supernovae observations strongly support the presence of a cosmological constant, but its value, which we will call apparent, is normally determined assuming that the Universe can be accurately described by a homogeneous model. Even in the presence of a cosmological constant we cannot excl...
