A cross-correlation of WMAP and ROSAT
J. M. Diego, J. Silk, W. Sliwa
We cross-correlate the recent CMB WMAP 1 year data with the diffuse soft X-ray background map of ROSAT. We look for common signatures due to galaxy clusters (SZ effect in CMB, brem…
Cosmological constraints from the cluster contribution to the power spectrum of the soft X-ray background. New evidence for a low sigma_8
J. M. Diego, W. Sliwa, J. Silk +2
We use the X-ray power spectrum of the ROSAT all-sky survey in the R6 band (approximately 0.9-1.3 keV) to set an upper limit on the galaxy cluster power spectrum. The cluster power…
The SZ effect contribution to WMAP. A Cross-Correlation between WMAP and ROSAT
J. M. Diego, J. Silk, W. Sliwa
We cross-correlate WMAP and ROSAT diffuse X-ray background maps and look for common features in both data sets. We use the power spectrum of the product maps and the cross-power sp…
The harmonic power spectrum of the soft X-ray background I. The data analysis
W. Sliwa, A. M. Soltan, M. J. Freyberg
Fluctuations of the soft X-ray background are investigated using harmonic analysis. A section of the ROSAT All-Sky Survey around the north galactic pole is used. The flux distribut…
