Redshifts of the Gravitational Lenses B1422+231 and PG 1115+080

B1422]231 and PG 1115]080 are gravitational lens systems that produce quadruple QSO images. In each, there is real promise that time delays can constrain the Hubble constant, and both belong to systems that can play an important role in modeling the lens potential. This article reports redshifts for the lensing galaxies and three neighboring galaxies in each of the two systems. B1422]231 comprises a group at z \ 0. 339 with a dispersion of 733 km s~1, and PG 1115]080 comprises a group at z \ 0. 311 with a dispersion of 326 km s~1. One of the neighboring galaxies in the B1422]231 system turned out to be an emission-line galaxy at z \ 0. 536, suggesting that QSO light passing through B1422]231 may have been subjected to lensing by a cluster at this more distant redshift. The velocity dispersion of the lensing galaxy in PG 1115]080 is determined to be 281 ²5 km s~1 (1A square aperture), which is surprisingly large, given the image splittings of in that system. 1A.
