Observational issues in radiometric and interferometric detection and analysis of the Sunyaev-Zel’dovich effects
نویسنده
چکیده
Radiometric observations using single dishes and interferometers are responsible for most detections of the Sunyaev-Zel’dovich (SZ) effects. This article discusses the techniques used in measuring the thermal and kinematic SZ effects in this way, the pitfalls that may arise, the systematic errors in the data, and the resulting uncertainties in the interpretation of the results. Since these uncertainties limit the physics return from SZ effect research, some approaches that would improve this situation are described. Longer reviews of SZ effect research (Rephaeli 1995; Birkinshaw 1999; Carlstrom, Holder and Reese 2002) may be consulted for additional details.

The 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...
متن کاملDetecting Sunyaev-Zel’dovich clusters with Planck: III. Properties of the expected SZ-cluster sample
The Planck mission is the most sensitive all-sky submillimetric mission currently being planned and prepared. Special emphasis is given to the observation of clusters of galaxies by their thermal Sunyaev-Zel’dovich (SZ) effect. In this work, the results of a simulation are presented that combines all-sky maps of the thermal and kinetic SZ-effect with cosmic microwave background (CMB) fluctuatio...
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 کاملSunyaev-Zel’dovich profiles and scaling relations: modelling effects and observational biases
We use high-resolution hydrodynamic re-simulations to investigate the properties of the thermal Sunyaev-Zel’dovich (SZ) effect from galaxy clusters. We compare results obtained using different physical models for the intracluster medium (ICM), and show how they modify the SZ emission in terms of cluster profiles and scaling relations. We also produce realistic mock observations to verify whethe...
متن کاملReconstructing the Peak Distribution in the Sunyaev-Zeldovich Effect Surveys
We examine the ability of the Sunyaev-Zel’dovich effect (SZE) statistics proposed by Lee (2002) using numerical simulations. The statistics describe the distribution of the peak heights in the noise-contaminated SZE sky maps, and provide an analysis technique to sort out the noise-contamination effect and estimate the number density of real clusters. The method is devised to be suitable for the...
