Wide field weak lensing observations of A 1689
We present a mass profile for A1689 from 0.13hMpc < r < 2hMpc from a weak lensing analysis of a 34′× 34′ R-band image from the ESO/MPG Wide Field Imager. We detect the gravitational shearing of a 23 < R < 25.5 background galaxy population even at the edge of the image with a 4σ significance, and find a two-dimensional mass reconstruction has a 13.4σ significance mass peak centered on the bright...
متن کاملWide field weak lensing observations of A 1835 and A 2204
We present mass reconstructions from weak lensing for the galaxy clusters A1835 and A2204 over 34′ × 34′ fields using data from the ESO/MPG Wide Field Imager. Using a background galaxy population of 22 < R < 25.5 we detect the gravitational shear of A1835 at 8.8σ significance, and obtain best-fit mass profiles of σv = 1233 −70 km/s for a singular isothermal sphere model and r200 = 1550h kpc, c ...
متن کاملA Deep, Wide-Field Weak Lensing Survey with MEGACAM
This brief document is a response to the call for ideas for CFHT imaging surveys with MEGACAM. We have been carrying out wide eld, deep imaging at the CFHT for several years now, with the primary science goal of using weak lensing of faint galaxies to probe the dark matter distribution on a range of scales from galaxy halos through galaxy cluster scales to supercluster scales. Thus far we have ...
متن کاملUsing Weak Lensing Dilution to Improve Measurements of the Luminous and Dark Matter in A1689
The E/SO sequence of a cluster defines a boundary redward of which a reliable weak lensing signal can be obtained from background galaxies, uncontaminated by cluster members. For bluer colors, both background and cluster galaxies are present, reducing the average distortion signal by the proportion of unlensed cluster members. In deep Subaru and HST/ACS images of A1689, we show that the tangent...
متن کاملLensing by Distant Clusters: Hst Observations of Weak Shear in the Field of 3c324
We present the detection of weak gravitational lensing in the eld of the radio galaxy 3C324 (z = 1:206) using deep HST imaging. From an analysis of the shapes of faint R = 24:5{27.5 galaxies in the eld we measure a weak, coherent distortion centered close to the radio source. This shear eld most likely arises from gravitational lensing of distant eld galaxies by a foreground mass concentration....
