Title: Planck SZ Clusters: Follow-up of the Planck Galaxy Cluster Catalog

Abstract: The Planck Sunyaev-Zel'dovich (SZ) galaxy cluster catalog is the first all-sky cluster catalog since those resulting from the ROSAT All- Sky Survey (RASS) of the early 1990s. It will be a powerful, new tool for the discovery and study of rare, massive clusters thanks to its large survey volume. Massive systems are invaluable as cosmological probes because of their high sensitivity to the expansion rate and hence to the presence and evolution of dark energy. We seek to measure velocity dispersions and estimate masses for a sample of massive Planck clusters in order to calibrate the all-important SZ-mass scaling relation crucial to cosmological applications of SZ cluster counts. Submitted on behalf of the Planck Multi-Wavelength Cluster Science Project, our program is part of a large follow-up effort underway on the Planck Cluster Catalog.
