Signs of WHIM in the soft X-ray background
A. M. Soltan, M. J. Freyberg, G. Hasinger
Small angular scale structure of the soft X-ray background correlated with the galaxy distribution is investigated. An extensive data sample from the ROSAT and XMM-Newton archives…
Testing the origin of the gamma-ray background
Andrzej M. Soltan, Radoslaw Marcinkowski
Fluctuations of the gamma-ray background (GRB) are investigated. It is assumed that the GRB is produced by discrete sources. Two basic classes of objects as dominant contributors t…
Search for correlations between COBE DMR and ROSAT PSPC All-Sky survey data
R. Kneissl, R. Egger, G. Hasinger +2
Results from a cross-correlation analysis between the COBE DMR 4 year, and ROSAT PSPC All-Sky Survey data are presented. Statistical comparisons between microwave and X-ray maps ca…
The large scale structure of the soft X-ray background. II: Galaxies
Andrzej M. Soltan, Guenther Hasinger, Roland Egger +2
The intensity of the soft X-Ray background is correlated with the distribution of galaxies. To demonstrate this, magnitude limited galaxy samples extracted from bright galaxy catal…
The large scale structure of the soft X-ray background. I: Clusters of galaxies
Andrzej M. Soltan, Guenther Hasinger, Roland Egger +2
Large-scale fluctuations of the X-ray background are investigated using the ROSAT All-Sky Survey. The autocorrelation function of the extragalactic background at 1 keV is determine…
