Merger induced scatter and bias in the cluster mass - Sunyaev-Zeldovich effect scaling relation
cosmology: large-scale structure of Universe, galaxies: clusters: general, meth- ods: N-body simulations
2011/10/20
We examine sources of scatter in scaling relations between galaxy cluster mass and thermal Sunyaev-Zeldovich (SZ) effect using cluster samples extracted from cosmological hydrodynamical simulations. O...
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...
