The galaxy alignment effect in Abell 1689: evolution, radial, and luminosity dependence.

HUNG L.-W., BANADOS E., DE PROPRIS R. and WEST M.J.

Abstract (from CDS):

We measure alignments on scales of 1 Mpc h–171 for galaxies in Abell 1689 (z = 0.18) from an existing Hubble Space Telescope mosaic. We find evidence of galaxy alignment in the inner 500 h–171kpc. The alignment appears to be stronger toward the center and is mostly present among the fainter galaxies, while bright galaxies are unaligned. This is consistent with a model where alignments originate from tidal locking.
