The Spectrum of the Black Hole X-ray Nova V404 Cygni in Quiescence as Measured by XMM-Newton
C. K. Bradley, R. I. Hynes, A. K. H. Kong +3
We present XMM observations of the black hole X-ray nova V404 Cygni in quiescence. Its quiescent spectrum can be best fitted by a simple power-law with slope 2. The spectra are con…
A universal radio/X-ray correlation in low/hard state black hole binaries
Elena Gallo, Rob Fender, Guy Pooley
We present a comprehensive study of (quasi-)simultaneous radio:X-ray observations of stellar black hole binaries during the spectrally hard X-ray state, finding evidence for a stro…
Chandra imaging spectroscopy of 1E 1740.7 - 2942
E. Gallo, R. Fender
We have observed the black hole candidate 1E 1740.7 - 2942, the brightest persistent hard X-ray source within a few degrees of the Galactic centre, for 10 ksec with Chandra (ACIS-I…
The effects of a comptonizing corona on the appearance of the reflection components in accreting black hole spectra
P. O. Petrucci, A. Merloni, A. Fabian +2
We discuss the effects of a comptonizing corona on the appearance of the reflection components, and in particular of the reflection hump, in the X-rays spectra of accreting black h…
