The results confirm the qualitative conclusion of Barrow, that a large density contrast is compatible with much smaller metric perturbations. The contribution of this peculiar gravity to the redshift might complicate studies of peculiar motions of galaxies, although it appears that the distortion is small for nearby clusters.337-340engCOSMOLOGYGALAXIES, CLUSTERINGRELATIVITYArtigo10.1086/169697WOS:A1991EX18500002Acesso restrito
