چکیده
We report the discovery of 4 new strong lensing systems by visual inspection of the Sloan Digital Sky Survey images of galaxy clusters in Data Release 6 (SDSS DR6). Two of them show Einstein rings, and the others show tangential giant arcs. These arcs or rings have large angle separations of > 8 from the bright central galaxies and show blue color compared to the red cluster galaxies. In addition, we also found 4 probable and 4 possible lenses by galaxy clusters. Subject headings: galaxies: clusters: general — gravitational lensing

Discovery of Strong Lensing Clusters in the Sdss Dr6
We discovered strong gravitational lensing in 4 galaxy clusters by visual inspection of the Sloan Digital Sky Survey images in Data Release 6 (SDSS DR6). Two of them show the Einstein rings, and the other two show tangential giant arcs. These arcs or rings have large angle separations of > 8 from the bright central galaxies. The lensed images in general are bluer than cluster member galaxies. T...
متن کاملGalaxy Clusters Identified from the Sdss Dr6 and Their Properties
Clusters of galaxies in most previous catalogs have redshifts z ≤ 0.3. Using the photometric redshifts of galaxies from the Sloan Digital Sky Survey Data Release 6 (SDSS DR6), we identify 39,716 clusters in the redshift range 0.05 < z < 0.6 with more than eight luminous (Mr ≤ −21) member galaxies. Cluster redshifts are estimated accurately with an uncertainty less than 0.022. The contamination ...
متن کاملObservations and Theoretical Implications of the Large Separation Lensed Quasar Sdss J1004+4112
We study the recently discovered gravitational lens SDSS J1004+4112, the first quasar lensed by a cluster of galaxies. It consists of four images with a maximum separation of 14.62. The system was selected from the photometric data of the Sloan Digital Sky Survey (SDSS), and has been confirmed as a lensed quasar at z = 1.734 on the basis of deep imaging and spectroscopic follow-up observations....
متن کاملEffects of Triaxiality on the Statistics of Large-separation Gravitational Lenses
We study the statistics of large-separation gravitational lens systems produced by non-spherical halos in the Cold Dark Matter (CDM) model. Specifically, we examine how the triaxiality of CDM halos affects the overall lensing probabilities and the relative numbers of different image configurations (double, quadruple, and naked cusp lenses). We find that triaxiality significantly enhances lensin...
متن کاملBackground sky obscuration by cluster galaxies as a source of systematic error for weak lensing
Lensing magnification and stacked shear measurements of galaxy clusters rely on measuring the density of background galaxies behind the clusters. The most common ways of measuring this quantity ignore the fact that some fraction of the sky is obscured by the cluster galaxies themselves, reducing the area in which background galaxies can be observed. We discuss the size of this effect in the Slo...
