" LoCuSS - A Definitive `Rosetta Stone' Survey of Galaxy Clusters at z=0.2 "
(University of Birmingham, UK)
The Local Cluster Substructure Survey (LoCuSS) is a study of a statistically
complete sample of 80 galaxy clusters at z=0.2 with the Subaru telescope, and
a wide range of space- and ground- based facilities. The main goals are (i)
to measure definitively the mass-observable scaling relations upon which
cluster-based attempts to measure the dark energy equation of state parameter
w will rely, and (ii) to measure the cluster-cluster scatter in the star-formation
rates and histories of galaxy clusters as part of a broad community-wide effort
to understand the physical origin of S0 galaxies. Our results will also define
a low-redshift benchmark that will aide the interpretation of the growing
menagerie of high-redshift cluster samples in the coming decades. I will present
an overview of the survey, and describe our recent results, including those
from our ongoing Herschel Key Programme of far-infrared observations with
PACS and SPIRE.
Seminars are also held at JAC,
