The Sunyaev-zel’dovich Effect with the Cosmic Background Imager
نویسندگان
چکیده
We are engaged in a program with the Cosmic Background Imager (CBI), a 13-element interferometer recently installed at 5000 m in the Chilean Andes, to measure H0 with 10% accuracy through observations of the Sunyaev-Zel’dovich effect in a sample of nearby clusters. We discuss the capabilities of this new instrument and present our cluster sample and selection criteria, along with results from detailed simulations. We also present preliminary observations of Abell 478.

An Unbiased Measurement of H0 through Cosmic Background Imager Observations of the Sunyaev-zel’dovich Effect in Nearby Galaxy Clusters
We present H0 results from Cosmic Background Imager (CBI) observations of the Sunyaev-Zel’dovich effect (SZE) in seven galaxy clusters, A85, A399, A401, A478, A754, A1651, and A2597. These observations are part of a program to study a complete, volume-limited sample of low-redshift (z < 0:1), X-ray–selected clusters. Our focus on nearby objects allows us to study a well-defined, orientation-unb...
متن کاملStatistics of the Sunyaev-Zel’dovich Effect power spectrum
Using large numbers of simulations of the microwave sky, incorporating the Cosmic Microwave Background (CMB) and the Sunyaev-Zel’dovich (SZ) effect due to clusters, we investigate the statistics of the power spectrum at microwave frequencies between spherical multipoles of 1000 and 10000. From these virtual sky maps, we find that the spectrum of the SZ effect has a larger standard deviation by ...
متن کاملThe Arcminute Microkelvin Imager
The Arcminute Microkelvin Imager is a dual array interferometer designed specifically to survey for galaxy clusters through detecting their Sunyaev-Zel’dovich signatures on the microwave background. Construction of the Small Array is now complete and commissioning observations have mapped several clusters. The Large Array is required to remove the effects of confusing radio sources and will all...
متن کاملRelativistic Corrections to the Sunyaev-zel’dovich Effect for Clusters of Galaxies. Ii. Inclusion of Peculiar Velocities
We extend the formalism of the relativistic thermal Sunyaev-Zel’dovich effect to the system moving with a velocity ~ β ≡ ~v/c with respect to the cosmic microwave background radiation. In the present formalism, the kinematic Sunyaev-Zel’dovich effect for the cluster of galaxies with a peculiar velocity ~ β is derived in a straightforward manner by the Lorentz boost of the generalized Kompaneets...
متن کاملThe Sunyaev-zel’dovich Effect
The Sunyaev-Zel’dovich effect causes a change in the apparent brightness of the Cosmic Microwave Background Radiation towards a cluster of galaxies or any other reservoir of hot plasma. Measurements of the effect provide distinctly different information about cluster properties than X-ray imaging data, while combining X-ray and Sunyaev-Zel’dovich effect data leads to new insights into the struc...
