The Red-Sequence Cluster Survey: first lensing results
Henk Hoekstra, H. K. C. Yee, Michael D. Gladders
The Red-Sequence Cluster Survey (RCS) is a 100 deg^2 galaxy cluster survey designed to provide a large sample of optically selected clusters of galaxies with redshifts 0.1<z<1.4. T…
HST large field weak lensing analysis of MS 2053-04: study of the mass distribution and mass-to-light ratio of X-ray selected clusters at 0.22<z<0.83
Henk Hoekstra, Marijn Franx, Konrad Kuijken +1
We have detected the weak lensing signal induced by the cluster of galaxies MS 2053-04 (z=0.58) from a two-colour mosaic of 6 HST WFPC2 images. The best fit singular isothermal sph…
Measurement of the bias parameter from weak lensing
Henk Hoekstra, Howard K. C. Yee, Michael D. Gladders
We have measured the correlation between the lensing signal induced by (dark) matter and number counts of galaxies on scales ranging from 0.15-3.0 h_{50}^{-1} Mpc (which correspond…
U, B and r band luminosity functions of galaxies in the Coma cluster
Marco Beijersbergen, Henk Hoekstra, Pieter G. van Dokkum +1
We present a deep multi-colour CCD mosaic of the Coma cluster (Abell 1656), covering 5.2 deg^2 in the B and r bands, and 1.3 deg^2 in the U band. This large, homogeneous data set p…
