SCALING RELATIONS AND OVERABUNDANCE OF MASSIVE CLUSTERS AT<i>z</i>≳ 1 FROM WEAK-LENSING STUDIES WITH THE<i>HUBBLE SPACE TELESCOPE</i>
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 signals and are well detected in their reconstructed two-dimensional mass maps. Combining the current results and our previous weak-lensing studies of five other high-z …
