چکیده

We present two weak lensing reconstructions of the nearby (zcl = 0.055) merging cluster Abell 3667, based on observations taken ∼ 1 year apart under different seeing conditions. This is the lowest redshift cluster with a weak lensing mass reconstruction to date. The reproducibility of features in the two mass maps demonstrate that weak lensing studies of low-redshift clusters are feasible. These data constitute the first results from an X-ray luminosity-selected weak lensing survey of 19 low-redshift (z < 0.1) southern clusters. Subject headings: galaxies: clusters: individual (Abell 3667), gravitational lensing

We analyze the mass content of the massive strong-lensing cluster Abell 586 (z = 0.17). We use optical data (imaging and spectroscopy) obtained with the Gemini Multi-Object Spectrograph (GMOS) mounted on the 8-m Gemini-North telescope, together with publicly available X-ray data taken with the Chandra space telescope. Employing different techniques – velocity distribution of galaxies, weak grav...

After a brief introduction to gravitational lensing theory, a rough overview of the types of gravitational lensing statistics that have been performed so far will be given. I shall then concentrate on recent results of galaxy-galaxy lensing, which indicate that galactic halos extend much further than can be probed via rotation of stars and gas.

We have observed the galaxy environments around two complete samples of radio-loud (steep-spectrum) and radio-quiet quasars (RLQ and RQQ) at 0.5 ≤ z ≤ 0.8 that are matched in B-luminosity, and find that the environments of both quasar populations are practically indistinguishable. A few objects are found in relatively rich clusters, but on average, they seem to prefer galaxy groups or clusters ...

We measure seeing-corrected ellipticities for 2 × 10 6 galaxies with magnitude R ≤ 23 in 12 widely separated fields totalling 75 deg 2 of sky. At angular scales 30 ′ , ellipticity correlations are detected at high significance and exhibit nearly the pure " E-mode " behavior expected of weak gravitational lensing. Even when smoothed to the full field size of 2.
