Re - examination of the Hubble Constant from the Sunyaev - Zel ' dovich E ect : Implication for Cosmological Parameters
نویسندگان
چکیده
We performed a systematic and comprehensive estimate of the Hubble constant H 0 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 0 , and the cosmological constant 0 . The resulting values of H 0 are largely consistent with that derived from the Cepheid distance for nearby galaxies. We discuss how the angular diameter distance d A vs. z diagram from the accurate SZ measurements of high-z clusters can distinguish the values of 0 and 0 .

E ect of Gravitational Lensing on Measurements of the Sunyaev - Zel ' dovich E ect
The Sunyaev{Zel'dovich (SZ) e ect of a cluster of galaxies is usually measured after background radio sources are removed from the cluster eld. Gravitational lensing by the cluster potential leads to a systematic de cit in the residual intensity of unresolved sources behind the cluster core relative to a control eld far from the cluster center. As a result, the measured decrement in the Rayleig...

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 distanc...

Sunyaev Zel’dovich cluster surveys can be used to constrain cosmological parameters. Extracting clusters from the primary anisotropies and the unresolved background from very faint clusters is simple when the telescope beam size is small (∼ 1′), but could be difficult if the beam is larger (∼ 8′). By reference to examples, we show that this is possible by carefully designing the depth of the su...
متن کامل1 A Measurement of the Hubble Constant from the X - Ray Properties and the Sunyaev - Zel ’ dovich Effect of CL 0016 + 16
A value of the Hubble constant has been determined from a comparison of the X-ray properties and Sunyaev-Zel’dovich effect of the distant rich cluster of galaxies CL 0016+16. The cluster, as imaged by the ROSAT PSPC, is significantly elliptical and we present the techniques we have developed to include this in our analysis. Assuming a smooth, isothermal gas distribution, we obtain a value H0 = ...
