Redshifts of the gravitational lenses MG 1131+0456 and B1938+666.
TONRY J.L. and KOCHANEK C.S.
Abstract (from CDS):
The redshifts of the gravitational lens galaxies in MG 1131+0456 and B1938+666 are 0.844 and 0.881, respectively. Both are early-type galaxies lying at the redshifts predicted by assuming that they are early-type galaxies with old stellar populations lying on the fundamental plane. We also find evidence for a foreground group of galaxies at z=0.343 near MG 1131+0456. The source redshifts are predicted to be ≳1.8 in both systems, but they are so red that infrared spectra will be required to determine their redshifts.
