An anti-correlation between X-ray luminosity and H-alpha equivalent width in X-ray binaries
R. P. Fender, D. M. Russell, C. Knigge +3
We report an anticorrelation between continuum luminosity and the equivalent width (EW) of the H-alpha emission line in X-ray binary systems. The effect is evident both in a univer…
Constraints on black hole accretion in V Puppis
Thomas J. Maccarone, Robert P. Fender, Christian Knigge +1
In light of the recent suggestion that the nearby eclipsing binary star system V Puppis has a dark companion on a long orbit, we present the results of radio and X-ray observations…
Broad-band X-ray spectral evolution of GX 339-4 during a state transition
M. Del Santo, T. M. Belloni, J. Homan +8
We report on X-ray and soft gamma-ray observations of the black-hole candidate GX 339-4 during its 2007 outburst, performed with the RXTE and INTEGRAL satellites. The hardness-inte…
Studying the X-ray hysteresis in GX 339-4: the disc and iron line over one decade
R. J. H. Dunn, R. P. Fender, E. G. Koerding +2
We report on a comprehensive and consistent investigation into the X-ray emission from GX 339-4. All public observations in the 11 year RXTE archive were analysed. Three different…
Broadband X-ray Spectra of GX 339-4 and the Geometry of Accreting Black Holes in the Hard State
John A. Tomsick, Emrah Kalemci, Philip Kaaret +6
A major question in the study of black hole binaries involves our understanding of the accretion geometry when the sources are in the hard state. In this state, the X-ray energy sp…
INTEGRAL/RossiXTE high-energy observation of a state transition of GX 339-4
T. Belloni, I. Parolin, M. Del Santo +7
On 2004 August 15, we observed a fast (shorter than 10 hours) state transition in the bright black-hole transient GX 339-4 simultaneously with RossiXTE and INTEGRAL. This transitio…
