Lens Model and Time Delay Predictions for the Sextuply Lensed Quasar SDSS J2222+2745
, 2016 SDSS J2222+2745 is a galaxy cluster at z=0.49, strongly lensing a quasar at z=2.805 into six widely separated images. In recent HST imaging of the field, we identify additional multiply lensed galaxies, and confirm the sixth quasar image that was ...

, 2002 In an ongoing infrared imaging survey of quasars at Keck Observatory, we have discovered that the z=1.285 quasar SDSS J233646.2-010732.6 comprises two point sources with a separation of 1.67". Resolved spectra show that one component is a standard quasar

Symposium - International Astronomical Union, 1972 I report here work done at Jodrell Bank by Mr John Gilbert and myself at a wavelength of 49 cm, on the degree of linear polarization, m49. For most sources the polarization is considerably reduced from its short wavelength value. We presume that most of this depolarization is by Faraday rotation, or rather by Faraday dispersion, between different parts
