Low-redshift formula for the luminosity distance in a LTB model with cosmological constant

ABSTRACT: We calculate the low-redshift Taylor expansion for the luminosity distance for an observer at the center of a spherically symmetric matter inhomogeneity with a nonvanishing cosmological constant. We then test the accuracy of the formulas comparing them to the numerical calculation for diff...
