Mass and Light in the Universe
Gillian Wilson
We present a weak lensing and photometric study of six half by half degree fields observed at the CFHT using the UH8K CCD mosaic camera. The fields were observed for a total of 2 h…
Large-Scale Cosmic Shear Measurements
Nick Kaiser, Gillian Wilson, Gerard A. Luppino
We present estimates of the gravitational lensing shear variance obtained from images taken at the CFHT using the UH8K CCD mosaic camera. Six fields were observed for a total of 1…
Weak Lensing Observations of High-Redshift Clusters of Galaxies
D. Clowe, G. Luppino, N. Kaiser +1
We present results of a weak gravitational lensing survey of six X-ray selected high-redshift clusters of galaxies. We find that the masses of the clusters derived from weak lensin…
A Photometric Study of the Supercluster MS0302 with the UH8K CCD Camera: Image Processing and Object Catalogs
N. Kaiser, G. Wilson, G. Luppino +1
We describe in detail the processing of a set of images of the z = 0.42 supercluster MS0302 taken with the UH8K camera at CFHT. The result of this is a pair of seamless combined V-…
A Photometric and Weak Lensing Analysis of the z=0.42 Supercluster MS0302+17
N. Kaiser, G. Wilson, G. Luppino +4
We perform a weak lensing and photometric study of the z=0.42 supercluster MS0302+17 using deep I and V band images taken with the UH8K CCD mosaic camera at the CFHT. We use archiv…
Detailed lensing properties of the MS2137-2353 core and reconstruction of sources
F. Hammer, P. Teyssandier, E. J. Shaya +3
A deep HST image of the MS 2137-2353 core has revealed detailed morphological structures in two arc systems, which are modelled and well reproduced after a complete analysis of the…
