The gravitational lens CFRS 14 . 1311 = HST 14176 + 5226

چکیده
Ratnatunga et al. (1995) have recently proposed that an object, HST 14176+5226, in the " Groth-Westphal " HST survey strip is an " Einstein cross " grav-itational lens. By chance, this object has been previously observed in the Canada-France Redshift Survey. The candidate lens, catalogued as CFRS14.1311, is an elliptical galaxy at z = 0.81. In addition, the spectrum shows a strong, spatially-extended, emission feature at 5342Å that almost certainly originates from two of the four " lensed " images. We tentatively identify this emission line as Ly α at z =3.4. A less prominent emission feature at 6822Å may be C IV 1549. Our data thus support the identification of this system as a new quadruple-image lens.

Gravitational lensing is an important tool for probing the mass distribution of galaxies. In this letter we report the discovery of a new quadruple lens HST 1411+5211 found in archived WFPC2 images of the galaxy cluster CL140933+5226. If the galaxy is a cluster member then its redshift is z = 0.46. The images of the source appear unresolved in the WFC implying that the source is a quasar. We ha...

An exquisite gravitational arc with a radius of 2. 1 has been discovered around the z = 0.938 field elliptical galaxy CFRS03.1077 during HST observations of Canada-France Redshift Survey (CFRS) fields. Spectroscopic observations of the arc show that the redshift of the resolved lensed galaxy is z = 2.941. This gravitational lens-source system is well-fitted using the position angle and elliptic...

We study the properties of a simple density distribution useful for modeling elliptical galaxies acting as gravitational lenses. The model closely corresponds to a model based on a physical scenario of violent relaxation and is analytic in its gravitational lensing properties for any ellipticity in the projected (surface) mass density. Besides the ellipticity, it has one free shape parameter wh...

We present Gemini integral-field unit (IFU) spectroscopy and Hubble Space Telescope (HST) F435Wand F814W-band images of a newly discovered four-image gravitational lens, SDSSJ140228.22+632133.3 (hereafter SDSSJ1402). The system was identified as one of 49 gravitational-lens candidates in the luminous red galaxy sample of the Sloan Digital Sky Survey, based on higher-redshift emission lines in t...

We investigate gravitational lens models for the quadruply-lensed Cloverleaf BAL QSO H1413+1143 based on the HST WFPC/WFPC2 astrometric and photometric data of the system by Turnshek et al. and the HST NICMOS-2 data by Falco et al. The accurate image positions and the dust-extinction-corrected relative amplifications, along with a possible detection of the lensing galaxy in the infrared, permit...
