Arrangement of galaxies with M_⋆ > 10⁹ M_⊙ in the parameter space σ₅ − M_⋆ (small gray dots). For each ringed galaxy (orange dot), its control group of non-ringed galaxies is shown (black dots, five nearest neighbors of equal z). The histograms show the distributions of each variable at each redshift for the ringed galaxies and their respective control samples. The p-values, obtained through a Kolmogorov-Smirnov (KS) test, representative of the goodness of fit of the distributions of both samples for each quantity, are displayed in their respective panels.
