A local infall from a cosmographic analysis of Pantheon+
Abstract
We present a model independent analysis of the Pantheon+ supernova sample and study the dependence of the recovered values of H0, q0 and j0 on the redshift cut and on the modeling of peculiar velocities. In addition to the bulk velocity discussed previously, we also find a significant infall that we attribute to the presence of an overdensity out to a radius of R 120h-1Mpc.
