The "universal" radio/X-ray flux correlation : the case study of the black hole GX 339-4

S. Corbel, M. Coriat, C. Brocksopp +5

The existing radio and X-ray flux correlation for Galactic black holes in the hard and quiescent states relies on a sample which is mostly dominated by two sources (GX 339-4 and V4…

Fast X-ray transients in the Galactic bulge with the Rossi X-ray Timing Explorer

David M. Smith, Craig B. Markwardt, Jean H. Swank +1

In X-ray binaries, rapid variability in X-ray flux of greater than an order of magnitude on time-scales of a day or less appears to be a signature of wind accretion from a supergia…
