Reflection and noise in the low spectral state of GX 339 - 4 .
نویسندگان
چکیده
We analyzed RXTE/PCA observations of GX339-4 in the low spectral state from 1996–1997. We found tight correlations between the QPO frequency and the spectral parameters of GX 339-4 X-ray emission. With the increase of the QPO frequency the slope of the primary power law and the amplitude of the reflected component increase. Frequency resolved spectral analysis showed, that the variability of the reflected component at frequencies higher than 1–10 Hz is suppressed in comparison with the variability of the primary power law component, similar to that observed earlier for Cyg X-1.

We present spectral fits and timing analysis of Rossi X-ray Timing Explorer observations of GX 339−4. These observations were carried out over a span of more than two years and encompassed both the soft/high and hard/low states. Two observations were simultaneous with Advanced Satellite for Cosmology and Astrophysics observations. Hysteresis in the soft state/hard state transition is observed. ...

We present results from spectral fitting of the very high state of GX339-4 with Nuclear Spectroscopic Telescope Array (NuSTAR) and Swift. We use relativistic reflection modeling to measure the spin of the black hole and inclination of the inner disk and find a spin of = + a 0.95 0.08 0.02 and inclination of 30°±1° (statistical errors). These values agree well with previous results from refle...
متن کاملA systematic look at the Very High and Low/Hard state of GX 339-4: Constraining the black hole spin with a new reflection model
We present a systematic study of GX 339-4 in both its very high and low hard states from simultaneous observations made with XMM-Newton and RXTE in 2004 and 2006. The X-ray spectra of both these extreme states exhibit strong reflection signatures, with a broad, skewed Fe-Kα line clearly visible above the continuum. Using a newly developed, self-consistent reflection model which implicitly inclu...

Previous work by Motch et al. (1985) suggested that in the low/hard state of GX 339−4, the soft X-ray power-law extrapolated backward in energy agrees with the IR flux level. Corbel and Fender (2002) later showed that the typical hard state radio power-law extrapolated forward in energy meets the backward extrapolated X-ray power-law at an IR spectral break, which was explicitly observed twice ...
متن کاملAccretion disc variability in the hard state of black hole X-ray binaries
XMM-Newton X-ray spectra of the hard state Black Hole X-Ray Binaries (BHXRBs) SWIFT J1753.5-0127 and GX 339-4 show evidence for accretion disc blackbody emission, in addition to hard power-laws. The soft and hard band Power-Spectral Densities (PSDs) of these sources demonstrate variability over a wide range of time-scales. However, on time-scales of tens of seconds, corresponding to the putativ...
