Anisotropic correlation function at redshifts z = 0, 0.5, 1, 1.5, and 2 for the central galaxies shape axes computed using stellar particles (top panel) and dark matter particles (bottom panel). The subpanels present the ratio between the correlation function along the $\widehat{a}$ and $\widehat{c}$ axes and the isotropic correlation function (dashed and dotted lines, respectively) for the five redshifts studied. The colours aid in tracking the evolution, as they get darker with increasing redshift.
