Gravitational lenses and lens candidates identified from the COSMOS field
Neal Jackson
A complete manual search has been carried out of the list of 285423 objects, nearly all of them galaxies, identified in the COSMOS field that are brighter than I=25. Two certain an…
ULAS J234311.93-005034.0: A gravitational lens system selected from UKIDSS and SDSS
Neal Jackson, Eran O. Ofek, Masamune Oguri
We report the discovery of a new gravitational lens system. This object, ULAS J234311.93-005034.0, is the first to be selected by using the new UKIRT Infrared Deep Sky Survey (UKID…
SDSS J131339.98+515128.3: A new gravitationally lensed quasar selected based on near-infrared excess
E. O. Ofek, M. Oguri, N. Jackson +2
We report the discovery of a new gravitationally lensed quasar, SDSS J131339.98+515128.3, at a redshift of 1.875 with an image separation of 1.24". The lensing galaxy is clearly de…
The polarization in the JVAS/CLASS flat-spectrum radio sources: II. A search for aligned radio polarizations
S. A. Joshi, R. A. Battye, I. W. A. Browne +3
We have used the very large JVAS/CLASS 8.4-GHz surveys of flat-spectrum radio sources to test the hypothesis that there is a systematic alignment of polarization position angle vec…
