    • A close separation double quasar lensed by a gas-rich galaxy 
      Gregg, Michael D.; Wisotzki, Lutz; Becker, Robert H.; Maza Sancho, José; Schechter, Paul L.; White, Richard L.; Brotherton, Michael S.; Winn, Joshua N. (The American Astronomical Society, 2000-06)
      In the course of a Cycle 8 snapshot imaging survey with the Space Telescope Imaging Spectrograph (STIS), we have discovered that the z\1.565 quasar HE 0512[3329 is a double with image separation 0A.644, di ering in ...
    • CTQ 414: a new gravitational lens 
      Morgan, Nicholas D.; Dressler, Alan; Maza Sancho, José; Schechter, Paul L.; Winn, Joshua N. (1999-10)
      We report the discovery and ground-based observations of the new gravitational lens CTQ 414. The source quasar lies at a redshift of z\1.29 with a B magnitude of 17.6. Ground-based optical imaging reveals two point sources ...
    • A NEARLY SYMMETRIC DOUBLE-IMAGE GRAVITATIONAL LENS 
      Winn, Joshua N.; Hewitt, Jacqueline N.; Patnaik, Alok R.; Schechter, Paul L.; Schommer, Robert A.; López Morales, Sebastián; Maza Sancho, José; Wachter, Stefanie (2001-03)
      We report the discovery of a new double-image gravitational lens, resulting from our search for lenses in the southern sky. Radio source PMN J2004[1349 is composed of two compact components separated by 1A.13 in VLA, ...
