Multi-object spectroscopy of the field surrounding PKS 2126-158: discovery of a z= 0.66 galaxy group.
WHITING M.T., WEBSTER R.L. and FRANCIS P.J.
Abstract (from CDS):
The galaxy group has five confirmed members, and a further four fainter galaxies are possibly associated. All confirmed members exhibit early-type galaxy spectra, a rare situation for a Mgii absorbing system. We discuss the relationship of this group to the absorbing gas, and the possibility of gravitational lensing of the quasar due to the intervening galaxies.
