LoCuSS: The Sunyaev-Zel'dovich Effect and Weak Lensing Mass Scaling Relation
dovich Effect Weak Lensing Mass Scaling Relation
2011/10/21
We present the first weak-lensing-based scaling relation between galaxy cluster mass, M_wl, and integrated Compton parameter Y_sph. Observations of 18 galaxy clusters at z~0.2 were obtained with the S...

Weak gravitational lensing has become an important method to determine the masses of galaxy clusters. The intrinsic shapes of the galaxies are a dominant source of uncertainty, but there are other lim...
