Low-redshift effects of local structure on the Hubble parameter in presence of a cosmological constant

ABSTRACT: In order to estimate the effects of a local structure on the Hubble parameter we calculate the low-redshift expansion for H(z) and δH H for an observer at the center of a spherically symmetric matter distribution in the presence of a cosmological constant. We then test the accuracy of the...
