Winn, JN and Morgan, ND and Hewitt, JN and Kochanek, CS and Lovell, JEJ and Patnaik, AR and Pindor, B and Schechter, PL and Schommer, RA, PMN J1632-0033: A New Gravitationally Lensed Quasar, The Astronomical Journal, 123, (1) pp. 10-19. ISSN 0004-6256 (2002) [Refereed Article]

We report the discovery of a gravitationally lensed quasar resulting from our survey for lenses in the southern sky. Radio images of J1632-0033 with the Very Large Array and the Australia Telescope Compact Array exhibit two compact, flat-spectrum components with separation 1.″47 and flux density ratio 13.2. Images with the Hubble Space Telescope reveal the optical counterparts to the radio components and also the lens galaxy. An optical spectrum of the bright component obtained with the first Magellan telescope reveals quasar emission lines at redshift 3.42. Deeper radio images with the Multi-Element Radio Linked Interferometry Network and the Very Long Baseline Array reveal a faint third radio component located near the center of the lens galaxy, which is either a third image of the background quasar or faint emission from the lens galaxy.
