Mapping of the Sunyaev-Zel'dovich effect in the cluster Cl 0016+16 with the Ryle Telescope
Abstract
We have mapped the high-redshift (z=0.546) cluster Cl 0016+16 with the Ryle Telescope at 15GHz. The Sunyaev-Zel'dovich decrement is clearly detected, and resolved. We combine our data with an X-ray image from ROSAT and a gas temperature from ASCA to estimate the Hubble constant H0=69-16+21kms-1Mpc-1 for an ΩM=1.0 cosmology, or H0=84-19+25kms-1Mpc-1 for ΩM=0.3 and ΩΛ=0.7.
