The Density Profile of Massive Galaxy Clusters from Weak Lensing
H. Dahle
We use measurements of weak gravitational shear around a sample of massive galaxy clusters at z = 0.3 to constrain their average radial density profile. Our results are consistent…

Weighing 40 X-ray Luminous Clusters of Galaxies with Weak Gravitational Lensing
H. Dahle
Deep two-color imaging of 40 clusters of galaxies with the NOT and the University of Hawaii 2.24-m telescope is used to measure the weak gravitational shear acting on faint backgro…
