Multi-wavelength Observations of the 2002 Outburst of Gx 339–4: Two Patterns of X-ray–optical/near-infrared Behavior
We report on quasi-simultaneous Rossi X-ray Timing Explorer and optical/near-infrared (nIR) observations of the black hole candidate X-ray transient GX 339–4. Our observations were made over a time span of more than eight months in 2002 and cover the initial rise and transition from a hard to a soft spectral state in X-rays. Two distinct patterns of correlated X-ray–optical/nIR behavior were fo...
متن کاملThe Off State of GX 339 – 4
We report BeppoSAX and optical observations of the black hole candidate GX339– 4 during its X-ray ‘off’ state in 1999. The broad-band (0.8–50 keV) X-ray emission can be fitted by a single power law with spectral index, α ∼ 1.6. The observed luminosity is 6.6 × 10 erg s in the 0.5–10 keV band, which is at the higher end of the flux distribution of black hole soft X-ray transients in quiescence, ...
متن کاملMOST Radio Monitoring of GX 339 − 4
The Molonglo Observatory Synthesis Telescope (MOST) has been monitoring the candidate Galactic black hole binary system GX339−4 at 843 MHz since 1994 April. We present the results of this program up to 1997 February and show a possible correlation between radio and X-ray light curves.
متن کاملOSSE Observations of GX 339 � 4
The Oriented Scintillation Spectrometer Experiment on the Compton Gamma Ray Observatory observed the Galactic black hole candidate GX 339?4 as a target of opportunity in 1991 September, in response to the outburst reported by BATSE. We report here on energy spectra in the 50 keV to 10 MeV range obtained by OSSE. The source was detected from 50 to 400 keV at a level relative to the Crab nebula o...
متن کاملThe evolution of the timing properties of the black - hole transient GX 339 – 4 during its 2002 / 2003 outburst
We present the results of the timing and color analysis of more than two hundred RXTE/PCA observations of the bright black-hole transient GX 339–4 obtained during its 2002/2003 outburst. The color-intensity evolution of the system, coupled to the properties of its fast time variability, allow the identification of four separate states. Depending on the state, strong noise is detected, together ...
