A Quadruple Lens System Found in the CLASSGravitational Lens SurveyS
The rst phase of a large gravitational lens survey using the Very Large Array at a wavelength of 3.6 cm has been completed, yielding images for 3258 radio sources. The Cosmic Lens All-Sky Survey, or CLASS, is designed to locate gravitational lens systems consisting of multiply-imaged compact components with separations > 0: 00 2. We report here the rst discovery of a gravitational lens from the...
متن کاملGravitational Quadruple Lens Produce 17 images ?
Gravitational lensing can be by a faint star, a trillion stars of a galaxy, or a cluster of galaxies, and this poses a familiar struggle between particle method and mean field method. In a bottom-up approach, a puzzle has been laid on whether a quadruple lens can produce 17 images. The number of images is governed by the gravitational lens equation, and the equation for n-tuple lenses suggests ...
متن کاملTime-delay Measurement for the Quadruple Lens Rx J1131−1231
We have measured the three time delays for the quadruple gravitational lens RX J1131−1231 using two seasons of monitoring data. The short delays between cusp images are A–B = 11.98 −1.27 days and A–C = 9.61 −1.57 days. The long A–D delay for the counter image is not as precisely determined because of the season gaps, but the data suggest a delay of −87±8 days. The short delays are difficult to ...
متن کاملMultifrequency Radio Observations of the Gravitational Lens System Mg 0414 + 0534
The four-image gravitational lens system MG 0414+0534 was observed with the GHz images reveal structure in the components which is consistent with that seen at other wavelengths. There was no detection of other extended emission, nor were there detections of the lensing galaxy or the " component x " seen in optical images. Detections of polarized emission show that the fractional polarized inte...

The rst phase of a large gravitational lens survey using the Very Large Array at a wavelength of 3.6 cm has been completed, yielding images for 3258 radio sources. The Cosmic Lens All-Sky Survey, or CLASS, is designed to locate gravitational lens systems consisting of multiply-imaged compact components with separations > 0: 00 2. From this rst phase has come the discovery of 1608+656, a quadrup...
