We have measured the Sunyaev–Zel'dovich (SZ) effect for a sample of 10 strong lensing selected galaxy clusters using the Sunyaev–Zel'dovich Array (SZA). The SZA is sensitive to structures on spatial scales of a few arcminutes, while the strong lensing mass modeling constrains the mass at small scales (typically <30″). Combining the two provides information about the projected concentrations of the strong lensing clusters. The Einstein radii we measure are twice as large as expected given the…

Efficient Mass Estimate at the Core of Strong Lensing Galaxy Clusters Using the Einstein Radius
In the era of large surveys, yielding thousands of galaxy clusters, efficient mass proxies at all scales are necessary in order to fully utilize clusters as cosmological probes. At the cores of
The Three-Dimensional Shapes of Galaxy Clusters
While clusters of galaxies are considered one of the most important cosmological probes, the standard spherical modelling of the dark matter and the intracluster medium is only a rough approximation.
Optical and Sunyaev–Zel'dovich observations of a new sample of distant rich galaxy clusters in the ROSAT All Sky
Finding a sample of the most massive clusters with redshifts $z>0.6$ can provide an interesting consistency check of the $\Lambda$ cold dark matter ($\Lambda$CDM) model. Here we present results from

The Einstein radius of a cluster provides a relatively model-independent measure of the mass density of a cluster within a projected radius of ∼150 kpc, large enough to be relatively unaffected by
