Observations of cooling neutron stars
J. E. Truemper
Observations of cooling neutron stars allow to measure photospheric radii and to constrain the equation of state of nuclear matter at high densities. In this paper we concentrate o…
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…
The X-Ray Luminosity Function of Active Galactic Nuclei
M. Schmidt, R. Giacconi, G. Hasinger +2
We derive an X-ray luminosity function for active galactic nuclei (AGN) that accounts for the X-ray source counts in the 0.5-2.0 and 2-10 keV energy ranges, the redshift distributi…
The ROSAT Deep Surveys
G. Hasinger, I. Lehmann, R. Giacconi +3
The ROSAT Deep Survey in the Lockman Hole is the most sensitive X-ray survey performed to date, encompassing an exposure time of 200 ksec with the PSPC and 1.2 Msec with the HRI. T…
The ROSAT Deep Survey IV. A distant lensing cluster of galaxies with a bright arc
G. Hasinger, R. Giacconi, J. E. Gunn +7
An unusual double-lobed extended X-ray source (RX J105343+5735) is detected in the ROSAT ultra-deep HRI image of the Lockman Hole. The angular size of the source is 1.7 X 0.7 arcmi…
The Neutron Star in the Supernova Remnant PKS 1209-52
V. E. Zavlin, G. G. Pavlov, J. Truemper
We re-analyzed soft X-ray data collected with the ROSAT and ASCA observatories on a candidate neutron star (NS) near the center of the supernova remnant PKS 1209-52. We fitted the…
