Comparison of the observed shell radii in NGC 474 with the modeled evolution of shell radii for Newtonian gravity and various choices of dark matter halos. Top two rows: illustration of the influence of the uncertainty arising due to the intrinsic scatter of the SHMR and HMCR. Bottom left: models of shell evolution for the preferred dark matter halo. Bottom right: models of shell evolution for the dark matter halo that lends the galaxy a similar gravitational potential as MOND.
