XMM-Newton observation of the Lockman Hole II. Spectral analysis
V. Mainieri, J. Bergeron, G. Hasinger +5
We present the results of the X-ray spectral analysis of the first deep X-ray survey with the XMM-Newton observatory during Performance Verification. We restrict the analysis to th…
The ROSAT Deep Survey: VI. X-ray sources and Optical identifications of the Ultra Deep Survey
I. Lehmann, G. Hasinger, M. Schmidt +10
We describe in this paper the ROSAT Ultra Deep Survey (UDS), an extension of the ROSAT Deep Survey (RDS) in the Lockman Hole. The UDS reaches a flux level of 1.2 x 10E-15 erg/cm2/s…
The contribution of Narrow-Line Seyfert 1 galaxies to the soft X-ray background
G. Hasinger, I. Lehmann, M. Schmidt +5
The ROSAT Ultradeep HRI survey in the Lockman Hole contains a complete sample of 91 X-ray sources with fluxes in the 0.5-2 keV band larger than 1.2 times 10e-15 erg cm-2 s-1, where…
The ROSAT Deep Survey: III. Optical spectral properties of X-ray sources in the Lockman Hole
I. Lehmann, G. Hasinger, M. Schmidt +6
The ROSAT Deep Survey in the Lockman Hole contains a complete sample of 50 X-ray sources with fluxes in the 0.5-2.0 keV band larger than 5.5E-15 erg/cm2/s. Previous work has provid…
The isolated neutron star candidate RBS1223 (1RXS J130848.6+212708)
A. D. Schwope, G. Hasinger, R. Schwarz +2
In the ROSAT Bright Survey (RBS) we have almost completely optically identified the brightest ~2000 high-galactic latitude sources from the ROSAT All-Sky Survey Bright Source Catal…
Evolution of the ROSAT AGN Luminosity Function
T. Miyaji, G. Hasinger, M. Schmidt
We present the results and parameterization of the 0.5-2 keV Luminosity Function of AGNs from various ROSAT Surveys, ranging from the ROSAT bright Survey from the ROSAT All-Sky Sur…
