B1359+154: A Six Image Lens Produced by a z=1 Compact Group of Galaxies
D. Rusin, C. S. Kochanek, M. Norbury +8
HST V and I-band observations show that the gravitational lens B1359+154 consists of six images of a single z_s=3.235 radio source and its star-forming host galaxy, produced by a c…
Evidence for Inconsistencies in Galaxy Luminosity Functions Defined by Spectral Type
C. S. Kochanek, M. A. Pahre, E. E. Falco
Galaxy morphological and spectroscopic types should be nearly independent of apparent magnitude in a local, magnitude-limited sample. Recent luminosity function surveys based on mo…
VLBI imaging of the gravitational lenses B1422+231 and MGJ0414+0534
E. Ros, J. C. Guirado, J. M. Marcaide +5
We present wide-field images of the quadruple gravitational lenses B1422+231 and MGJ0414+0534 obtained from global Very Long Baseline Interferometry (VLBI) observations at 8.4 GHz…
PMN J1838-3427: A new gravitationally lensed quasar
Joshua N. Winn, Jacqueline N. Hewitt, Paul L. Schechter +11
We report the discovery of a new double-image quasar that was found during a search for gravitational lenses in the southern sky. Radio source PMN J1838-3427 is composed of two fla…
Multi-Frequency Analysis of the New Wide-Separation Gravitational Lens Candidate RX J0921+4529
J. A. Munoz, E. E. Falco, C. S. Kochanek +9
We report the discovery of a new two-image gravitational lens candidate. The system RX J0921+4529 contains two z_s=1.66 quasars separated by 6."93 with an H band magnitude differen…
The Host Galaxy of the Lensed Quasar Q 0957+561
C. R. Keeton, E. E. Falco, C. D. Impey +6
Infrared images of the Q 0957+561 gravitational lens obtained with the Hubble Space Telescope show two large (\sim 5 arcsec) lensed images of the z_s=1.41 quasar host galaxy. Parts…
