2XMM J100451.6+411627: A cool core cluster at z=0.82
Matthias Hoeft, Georg Lamer, Jan Kohnert +1
- Aims: Gas cooling in the centre of massive galaxy clusters is believed to feed the most powerful active galactic nuclei in the Universe. How often clusters at high redshift show…
2XMM J083026+524133: The most X-ray luminous cluster at redshift 1
G. Lamer, M. Hoeft, J. Kohnert +2
In the distant universe X-ray luminous clusters of galaxies are rare objects. Large area surveys are therefore needed to probe the high luminosity end of the cluster population at…
Proper motions of ROSAT discovered isolated neutron stars measured with Chandra: First X-ray measurement of the large proper motion of RX J1308.6+2127/RBS 1223
C. Motch, A. M. Pires, F. Haberl +2
The unprecedented spatial resolution of the Chandra observatory opens the possibility to detect with relatively high accuracy proper motions at X-ray wavelengths. We have conducted…
The ultra-compact binary candidate KUV 23182+1007 is a bright quasar
John Southworth, A. Schwope, B. T. Gaensicke +1
KUV 23182+1007 was identified as a blue object in the Kiso UV Survey in the 1980s. Classification-dispersion spectroscopy showed a featureless continuum except for a strong emissio…
X-rays from Cataclysmic Variables
Erik Kuulkers, Andrew Norton, Axel Schwope +1
Cataclysmic Variables are a distinct class of interacting binaries, transferring mass from a donor star to a degenerate accretor, a white dwarf. We here review X-ray observations o…
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…
