    $\begingroup$ Relative to the center of the supercluster is not the same as relative to earth. And probably the red shift due to distance is subtracted and only the residuals looked at $\endgroup$

    $\begingroup$ Please provide references to measurements that show galaxies in the Laniakea supercluster are moving towards us. $\endgroup$

  • $\begingroup$ While the galaxies you mentioned might not actually be moving toward us, your premis still holds, in that there are galaxies moving towards each other. Hubble's observation is intended to be interpreted at a larger scale, in general galaxies move away from each other based on their distance. $\endgroup$
