X-Ray Properties of three Clusters of Galaxies and their Implications for the Sunyaev-Zeldovich Effect
Abstract
We present the preparation for an observation of the Sunyaev-Zeldovich (SZ) effect with the 100m telescope in Effelsberg. We calculate the expected diminution of the cosmic microwave background radiation (CMB) at radio wavelength towards a small sample of clusters of galaxies: A85, A665, and Cl0016+16. We obtain the required parameters from the X-ray analysis of ROSAT PSPC data of these clusters. We derive expected central diminutions ΔTR,max of -(440 180)μK for A665 and -(810 680)μK for Cl0016+16. For the cluster A85 we find evidence for a cooling flow. The best candidate for a SZ measurement is the cluster 0016+16.
