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…

Strong and weak lensing analysis of cluster Abell 2219 based on optical and near infrared data
J. Bezecourt, H. Hoekstra, M. E. Gray +3
We present a gravitational lensing study of the massive galaxy cluster A2219 (redshift 0.22). This investigation is based on multicolour images from U through H, which allows photo…

Mass and mass-to-light ratio of galaxy groups from weak lensing
Henk Hoekstra, Marijn Franx, Konrad Kuijken
We have measured for the first time the weak lensing signal due to groups of galaxies. The groups are at intermediate redshifts, and have been identified in the CNOC2 field survey,…
