Scaling Relations and Overabundance of Massive Clusters at z>~1 from Weak-Lensing Studies with HST

M. J. Jee, K. S. Dawson, H. Hoekstra +22

We present weak gravitational lensing analysis of 22 high-redshift (z >~1) clusters based on Hubble Space Telescope images. Most clusters in our sample provide significant lensing…
