Title: Scaling Relations of Distant, SZ-confirmed XXL Galaxy Clusters
PI Name: Adam Mantz
We propose to follow up four distant galaxy clusters discovered by the XMM-LSS
and XXL survey programs. In addition to being confirmed with optical and NIR
spectroscopy or photometry, the presence of hot gas in each of these clusters
has been confirmed through a significant detection of the Sunyaev-Zel dovich
signal with CARMA. Three of our targets have redshifts greater than 1, with one
of them at 1.5. Deeper XMM data will allow us to situate these high-redshift
clusters on X-ray and SZ scaling relations and provide key mass proxies,
enhancing the cosmological power of the XXL survey and enabling a variety of
studies of cluster evolution. We also request joint Chandra observations in
order to constrain and remove point-source contamination of the XMM signal for
these faint clusters.
