Abstract

We seek to measure velocity dispersions and estimate masses for a sample of the Planck Sunyaev-Zel'dovich (SZ) galaxy clusters. This will allow us to calibrate the all-important SZ-mass relation crucial to cosmological applications of SZ cluster counts to constrain dark energy. Our sample is notably rich in massive systems, the most sensitive probes of the expansion rate and dark energy. Submitted on behalf of the PLANCK working group on clusters and secondary anisotropies, our program is part of a large follow-up effort underway on the Planck Cluster Catalog.
