Abstract
Gravitational lensing is an important tool for probing the mass distribution of galaxies. In this Letter, we report the discovery of a new quadruple lens HST 1411+5211 found in archived Wide-Field Planetary Camera 2 images of the galaxy cluster CL 140933+5226. If the galaxy is a cluster member, then its redshift is z=0.46. The images of the source appear unresolved in the Wide-Field Camera, implying that the source is a quasar. We have modeled the lens as both a single galaxy and a galaxy plus a cluster. The latter model yields excellent fits to the image positions along with reasonable parameters for the galaxy and cluster, making HST 1411+5211 a likely gravitational lens. Determination of the source redshift and confirmation of the lens redshift would allow us to put strong constraints on the mass distribution of the lensing galaxy.Keywords
