``Sunyaev-Zel'dovich Determined Distances to High Redshift Galaxy Clusters"
|
Abstract
We present preliminary results from a maximum likelihood joint
analysis of 30 GHz interferometric Sunyaev-Zel'dovich Effect (SZE) and
X-ray observations for a sample of 14 high redshift (0.14 leq z leq
0.78) clusters of galaxies. From the joint SZE and X-ray analysis we
determine the distances to the 14 galaxy clusters. These distances
imply a Hubble parameter of 63^{+4}_{-4}^{+19}_{-19} km s^{-1}
Mpc^{-1} for a Omega_M=0.3 and Omega_Lambda=0.7 cosmology, where the
uncertanties are statistical followed by systematic at 68 %
confidence. The implied Hubble constant is 59 ksM for an open
Omega_M=0.3 universe and 56 ksM for a flat Omega_M=1 cosmology. We
briefly discuss possible sources of systematic uncertainty and their
controllable nature.
