'The Suprime Survey: A Large Shear-selected Sample of Galaxy Clusters at z = 0.1-0.8'

The Suprime survey consists of 22 square degrees of deep imaging with Suprime-Cam
on the Subaru Telescope. Weak lensing analysis of these images and subsequent
spectroscopic follow-up have produced the first large shear-selected sample of
galaxy clusters. Clusters range in mass from 0.8-5e14 solar masses and cover the
redshift range z = 0.1-0.8, although though the exact sensitivity of the survey
depends strongly on the observing conditions and data quality in each field. I
will discuss constraints on the equation of state and the amplitude of the power
spectrum based on the highest quality data. These are not particularly strong for
the current sample, but give a sense of the prospects for future lensing surveys.
I will also discuss some other "value-added" analysis that could be applied to
similar samples of clusters detected by lensing, X-ray, SZ or other means.
