The XMM-Newton Bright Serendipitous Source Sample (XMM-Newton BSS)
R. Della Ceca, T. Maccacaro, A. Caccianiga +15
The XMM-Newton Survey Science Center is constructing a large (~1000 sources) and complete sample of bright serendipitous XMM-Newton sources at high galactic latitude, so as to allo…
Probing the gas content of the dwarf galaxy NGC 3109 with background X-ray sources
P. Kahabka, T. H. Puzia, W. Pietsch
We established the catalog of X-ray point sources in the field of the Magellanic-type spiral galaxy NGC 3109 (DDO 236) from two ROSAT PSPC observations. Of the 91 X-ray sources 26…
RX J0420.0-5022: An isolated neutron star candidate with evidence for 22.7 s X-ray pulsations
F. Haberl, W. Pietsch, C. Motch
We report the discovery of a new isolated neutron star candidate, RX J0420.0-5022, showing evidence (4 sigma) for 22.7 s X-ray pulsations in ROSAT data. NTT observations of the fie…
Peculiar properties of 2 unusually X-ray bright early type galaxies
G. Trinchieri, W. Pietsch
Two X-ray bright early type galaxies, selected for their unusually high X-ray to optical flux ratio, have been observed at high spatial resolution with the ROSAT HRI. Both sources…
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…
NGC 3079: X-ray emission from the nuclear super-bubble and halo
W. Pietsch, G. Trinchieri, A. Vogler
We report the results of the spatial and spectral analysis of the ROSAT HRI and PSPC observations of the edge-on spiral galaxy NGC 3079. We detected several sources in the field of…
