Time-resolved X-Shooter spectra and RXTE light curves of the ultra-compact X-ray binary candidate 4U 0614+091
O. K. Madej, P. G. Jonker, P. J. Groot +3
In this paper we present X-Shooter time resolved spectroscopy and RXTE PCA light curves of the ultra-compact X-ray binary candidate 4U 0614+091. The X-Shooter data are compared to…
CXOGBSJ174444.7-260330: a new long orbital period cataclysmic variable in a low state
E. M. Ratti, T. F. J. van Grunsven, P. G. Jonker +12
We present phase-resolved spectroscopy and photometry of a source discovered with the Chandra Galactic Bulge Survey (GBS), CXOGBSJ174444.7-260330 (aka CX93 and CX153 in the previou…
The nature of the bright ULX X-2 in NGC3921: a Chandra position and HST candidate counterpart
P. G. Jonker, M. Heida, M. A. P. Torres +6
We report on Chandra observations of the bright ultra-luminous X-ray (ULX) source in NGC3921. Previous XMM observations reported in the literature show the presence of a bright ULX…
The black hole candidate MAXIJ1659-152 in and towards quiescence in X-ray and radio
Peter G. Jonker, James C. A. Miller-Jones, J. Homan +5
In this paper we report on Expanded Very Large Array radio and Chandra and Swift X-ray observations of the outburst decay of the transient black hole candidate MAXI J1659-152 in 20…
The black hole candidate XTE J1752-223 towards and in quiescence: optical and simultaneous X-ray - radio observations
E. M. Ratti, P. G. Jonker, J. C. A. Miller-Jones +10
We present optical, X-ray and radio observations of the black hole transient (BHT) XTE J1752-223 towards and in quiescence. Optical photometry shows that the quiescent magnitude of…
