Relations between X-ray timing features and spectral parameters of Galactic black hole X-ray binaries

Understand

We present a study of correlations between spectral and timing parameters for a sample of black hole X-ray binary candidates.

• Data are taken from GX 339-4, H 1743-322, and XTE J1650-500, as the Rossi X-ray Timing Explorer (RXTE) observed complete outbursts of these sources.
• In our study we investigate outbursts that happened before the end of 2009 to make use of the high-energy coverage of the HEXTE detector and select observations that show a certain type of quasi-periodic oscillations (type-C QPOs).
• The spectral parameters are derived using the empirical convolution model simpl to model the Comptonized component of the emission together with a disc blackbody for the emission of the accretion disc.
