A search for soft X-ray emission associated with prominent high-velocity-cloud complexes
J. Kerp, W. B. Burton, R. Egger +5
We correlate the ROSAT 1/4 keV all-sky survey with the Leiden/Dwingeloo HI survey, looking for soft X-ray signatures of prominent high-velocity-cloud (HVC) complexes. We study the…
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…
A Large-Area Cross-Correlation Study of High Galactic Latutude Soft and Hard X-ray Skies
Takamitsu Miyaji, Guenther Hasinger, Roland Egger +2
We have made cross-correlation analyses of (2 -- 15 keV) HEAO A2 and 1 keV ROSAT PSPC All-Sky Survey maps over a selected area ( 4000 deg) with high galactic latitude (b>…
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…
G272.2--3.2: A centrally filled and possibly young SNR discovered by ROSAT
J. Greiner, R. Egger, B. Aschenbach
We report the discovery of a new SNR in the \ros All-Sky-Survey data. The SNR has a nearly circular shape with a diameter of about 15 arcmin. The surface brightness is rather unifo…
