Discovery of a Probable Gravitational Lens

Abstract

We report the discovery of a new probable gravitational lens system, associated with the quasar UM 425 = 1120+019, at z = 1.465. The optical image of the system consists of 4 or more components. The two well-observed brightest components have very similar spectra. The difference of the two spectra (scaled appropriately) is consistent with a spectrum of a galaxy at z ≃ 0.6. There is a large number of faint galaxies in the field, suggestive of a lensing cluster at that redshift.
