متن کاملA New Quadruple Gravitational Lens System: CLASS B0128+437
High resolution MERLIN observations of a newly-discovered four-image gravitational lens system, B0128+437, are presented. The system was found after a careful reanalysis of the entire CLASS dataset. The MERLIN observations resolve four components in a characteristic quadruple-image configuration; the maximum image separation is 542 mas and the total flux density is 48 mJy at 5 GHz. A best-fit l...
متن کاملA 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 کاملHST Observations of the Gravitational Lens Systems
High angular resolution PC1 images of the gravitational lens systems HE 1104−1805 and J03.13 are presented. Using a method described in Remy et al. (1997a), optimal TinyTim PSFs are constructed to fit at best the lensed pointlike components. The derived photometry of the GL components and the detection of the lens galaxy for HE 1104-1805 are discussed. Textbook case FOS spectra of J03.13 A and ...
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 ...
