ASCA OBSERVATION OF THE HIGH X-RAY LUMINOSITY CLUSTER ABELL1423
ABSTRACT
We propose to observe the high X-ray luminosity cluster Abell 1423 (z=0.21). The ASCA data will be combined with ROSAT HRI data and a map of the Sunyaev-Zel'dovich decrement from the Ryle Telescope to constrain the properties of the cluster and derive an estimate of the Hubble Constant. The proposed target is part of a large sample for which we have ROSAT, ASCA and Ryle data that will permit the direct determination of the cluster temperature function at a redshift of 0.2 and provide a sample of S-Z detections free from gross projection effects.
