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…
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…
The X-ray stream-eclipsing polar RX J1802.1+1804
J. Greiner, R. A. Remillard, C. Motch
We present X-ray and optical data of the newly discovered AM Her variable RX J1802.1+1804 = V884 Her. This X-ray source was observed in the ROSAT All-Sky-Survey in September 1990 a…
The Optical Content of the Error Box of GRS 1915+105
Michel Boer, Jochen Greiner, Christian Motch
We report on deep photometry and spectroscopy of the objects detected in the ROSAT HRI X-ray error box of the hard X-ray transient, GRS 1915+105. The probable counterpart of this s…
