The WMAP Q, V, and W band radial profiles of temperature deviation of the cosmic microwave background (CMB) were constructed for a sample of 31 randomly selected nearby clusters of galaxies in directions of Galactic latitude $|b| >$ 30$^o$. The profiles were compared in detail with the expected CMB Sunyaev-Zel'dovich effect (SZE) caused by these clusters, with the hot gas properties of each cluster inferred observationally by applying gas temperatures as measured by ASCA to isothermal $\beta…

The Sunyaev-Zel'dovich Effect of Nearby Clusters in the 3-Year WMAP Data
Abstract We explore the thermal Sunyaev-Zel'dovich (SZ) effect of a sample of 31 clusters in the three-year data of the Wilkinson Microwave Anisotropy Probe (WMAP), and detect strong SZ signal at the
Looking for the Sunyaev-Zel'dovich effect in the Virgo cluster from WMAP and ROSAT data
Wilkinson Microwave Anisotropy Probe (WMAP) observations at millimetre wavelengths are sensitive to the Sunyaev–Zel’dovich (SZ) effect in galaxy clusters. Among all the objects in the sky, the Virgo

Using Wilkinson Microwave Anisotropy Probe (WMAP) five year data, we look for the average Sunyaev-Zel'dovich effect (SZE) signal from clusters of galaxies by stacking the regions around hundreds of

Analysis of the Amplitude of the Sunyaev-Zel'dovich Effect out to Redshift z=0.8
The interaction of the cosmic microwave background (CMB) with the hot gas in clusters of galaxies, the so-called Sunyaev--Zel'dovich (SZ) effect, is a very useful tool that allows us to determine the
Missing thermal energy of the intracluster medium
The Sunyaev‐Zel’dovich (SZ) effect is a direct probe of thermal energy content of the Universe, induced in the cosmic microwave background (CMB) sky through scattering of CMB photons off hot
The Planck 2015 model prediction mismatch of Sunyaev-Zel’dovich cluster counts and a universal microwave background composed of redshifted radiation from ‘dark’ matter
The PLANCK 2015 model predictions do not match the observed Sunyaev-Zeldovich cluster counts well. The discrepancy increasing towards lower signal-to-noise thresholds suggests that the data favor a

Taking advantage of the all-sky coverage and broad frequency range of the Planck satellite, we study the Sunyaev-Zeldovich (SZ) and pressure profiles of 62 nearby massive clusters detected at high

Galaxy clusters are the most massive objects in the Universe and comprise a high-temperature intracluster medium of about 10 7 K, believed to offer a main foreground effect for cosmic microwave
