Abstract:

Rich cluster CL 0016+16 lies in a large-scale dynamical structure at redshift , and has a strong Sunyaev-Zel'dovich effect. When the X-ray and radio data for CL 0016+16 are interpreted in terms of the cluster distance, this cluster provides the highest redshift datum on the Hubble diagram based on the Sunyaev-Zel'dovich effect, with a Hubble constant of . There is significant model-dependence in this estimate. Systematic effects presently limit the accuracy with which can be deduced from the Hubble diagram, but it appears that .
