Re-examination of the Hubble Constant from the Sunyaev-Zel'dovich Effect: Implication for Cosmological Parameters
Shiho Kobayashi, Shin Sasaki, Yasushi Suto
Abstract
We performed a systematic and comprehensive estimate of the Hubble constant H0 via the Sunyaev-Zel'dovich temperature decrement and the X-ray measurements for clusters up to the redshift z=0.541, with particular attention to its dependence on the density parameter Ω0, and the cosmological constant λ0. The resulting values of H0 are largely consistent with that derived from the Cepheid distance for nearby galaxies. We discuss how the angular diameter distance dA vs. z diagram from the accurate SZ measurements of high-z clusters can distinguish the values of Ω0 and λ0.
