Abstract

The beginning of the cosmological phase bearing the direct kinematic imprints of supernovae (SNe) dimming may significantly vary within different models of late-time cosmology, even if such models are able to fit present SNe data at a comparable level of statistical accuracy. This effect—useful in principle to discriminate among different physical interpretations of the luminosity– redshift relation—is illustrated here with a pedagogical example based on the Lemaˆıtre–Tolman–Bondi geometry.
