Based on their radial velocities, they could have interacted with the MW at fairly high redshifts, but such galaxies do actually exist. I still completely agree with the importance of low luminosity galaxies as tracers of environmental effects.dweiszhttps://www.blogger.com/profile/18392461084941294078noreply@blogger.com
