An X-ray Galaxy Cluster Survey for Investigations of Dark Energy
Z. Haiman, S. Allen, N. Bahcall +34
The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…
The ROSAT HRI Point Spread Function
Peter Predehl, Almudena Prieto
A sample of the brightest point-like sources observed with the ROSAT-HRI were analysed to asses on the intrinsic shape of the ROSAT-HRI Point Spread Function (PSF). Almost all of t…
CHANDRA observation of the narrow-line Seyfert 1 galaxy IRAS 13224-3809
F. Pfefferkorn, Th. Boller, V. Burwitz +1
The narrow-line Seyfert 1 galaxy (NLS1) IRAS 13224-3809 has been observed with the CHANDRA High Resolution Camera (HRC-I) for 12 ksec on February, 2, 2000. The source was proposed…
The ROSAT All-Sky Survey Bright Source Catalogue
Wolfgang Voges, Bernd Aschenbach, Thomas Boller +16
We present the ROSAT All-Sky Survey Bright Source Catalogue (RASS-BSC, revision 1RXS) derived from the all-sky survey performed during the first half year (1990/91) of the ROSAT mi…
Observations of the Galactic Center Region with Beppo-Sax
L. Sidoli, S. Mereghetti
We are performing a survey of the Galactic Center region with the BeppoSAX satellite. Several known point sources are visible (including one at the position of SgrA*), as well as n…
ROSAT observation of GRS 1739-278
J. Greiner, K. Dennerl, P. Predehl
We have observed GRS 1739-278 with the ROSAT HRI on March 31, 1996. The improved X-ray position proves the identification with an earlier discovered variable radio source. We deriv…
