Query: First Results On Shear-Selected Clusters From the Deep Lens Survey:
  Optical Imaging, Spectroscopy, and X-ray Followup   We present the first sample of galaxy clusters selected on the basis of their
weak gravitational lensing shear. The shear induced by a cluster is a function
of its mass profile and its redshift relative to the background galaxies being
sheared; in contrast to more traditional methods of selecting clusters, shear
selection does not depend on the cluster's star formation history, baryon
content, or dynamical state. Because mass is the property of clusters which
provides constraints on cosmological parameters, the dependence on these other
parameters could induce potentially important biases in traditionally-selected
samples. Comparison of a shear-selected sample with optically and X-ray
selected samples is therefore of great importance. Here we present the first
step toward a new shear-selected sample: the selection of cluster candidates
from the first 8.6 deg$^2$ of the 20 deg$^2$ Deep Lens Survey (DLS), and
tabulation of their basic properties such as redshifts and optical and X-ray
counterparts.
