ADC_Keywords: Clusters, galaxy ; Gravitational lensing ; QSOs ; Redshifts Keywords: galaxies: clusters: general - galaxies: halos - gravitational lensing - quasars: individual (MG 0751+2716, BRI 0952-0115, PG 1115+080, B1422+231, MG 1654+1346, PMN J2004-1349, B2114+022, HE 2149-2745) Abstract: We present the first results from our spectroscopic survey of strong gravitational lens environments. Six of the eight lens galaxies in our sample belong to a poor group of galaxies, three of which are newly discovered here (those associated with BRI 0952-0115, MG 1654+1346, and B2114+022). Description: We first identified galaxies for follow-up spectroscopy from two-color, wide-field imaging of each lens field. We obtained deep images in I and either V or R during the period from 2002 May to 2004 June using the 36'x36' Mosaic Imager on the 4m telescopes at Kitt Peak National Observatory and Cerro Tololo Inter-American Observatory.

Note (2): Within a fixed physical size of ∼6.5kpc (see Williams et al. 2006ApJ...646...85W). Note (3): Method from which the velocity was obtained, defined as follows: 1 = absorption lines; 2 = emission lines; 3 = combination of absorption and emission lines.
