Mass calibration of SPT clusters: re-observation of missing pointings
Abstract
(Abridged) The South Pole Telescope (SPT) galaxy cluster survey identified via the Sunyaev-Zel'dovich (SZ) effect 158 massive clusters from its initial 720 deg2 area. We are proposing to combine XMM-Newton, SPT, and weak lensing measurements for a sample of 20 intermediate redshift (0.3<z<0.5) uniformly selected by their SPT detection significance from 560 deg2 survey area. These clusters will also have ground-based observations weak lensing measurements and in some cases also dynamical masses. Here we propose to complete the X-ray follow-up of the intermediate redshift calibration sample to uniform sensitivity and selection by observing the last 4 clusters without X-ray data and re-observing 4 clusters strongly affected by soft proton flaring.
