The X-ray Properties of Weak Lensing Selected Galaxy Clusters
  We present the results of an X-ray follow-up campaign targeting 10 Weak
Lensing (WL) selected galaxy clusters from a Subaru WL survey. Eight clusters
were studied with dedicated Chandra pointings, whereas archival X-ray data were
used for the remaining two clusters. The WL clusters appear to fit the same
scaling relation between X-ray luminosity and temperature as X-ray selected
clusters. However, when we consider the luminosity-mass relation, the WL
selected clusters appear underluminous by a factor 3.9$\pm$0.9 (or,
alternatively, more massive by 2.9$\pm$0.2), compared to X-ray selected
clusters. Only by considering various observational effects that could
potentially bias WL masses, can this difference be reconciled. We used X-ray
imaging data to quantify the dynamical state of the clusters and found that one
of the clusters appears dynamically relaxed, and two of the clusters host a
cool core, consistent with Sunyaev-Zel'dovich effect selected clusters. Our
results suggest that regular, cool core clusters may be over-represented in
X-ray selected samples.
