Overview of an Extensive Multi-wavelength Study of GX 339-4 during the 2010 Outburst

Abstract

The microquasar GX 339-4 experienced a new outburst in 2010: it was observed simultaneously at various wavelengths from radio up to soft gamma-rays. We focused on observations that are quasi-simultaneous with those made with the INTEGRAL and RXTE satellites: these were collected in 2010 March-April during our INTEGRAL Target of Opportunity program, and during some of the other INTEGRAL observing programs with GX 339-4 in the field-of-view. X-ray transients are extreme systems that often harbour a black hole, and are known to emit throughout the whole electromagnetic spectrum when in outburst. The goals of our program are to understand the evolution of the physical processes close to the black hole and to study the connections between the accretion and ejection. We analysed radio, NIR, optical, UV, X-ray and soft gamma-ray observations. We studied the source evolution in detail by producing light curves, hardness-intensity diagrams and spectra. We fitted the broadband data with phenomenological, then physical, models to study the emission coming from the distinct components. Based on the energy spectra, the source evolved from the canonical hard state to the canonical soft state. The source showed X-ray spectral variations that were correlated with changes in radio, NIR and optical emission. The bolometric flux increased from 0.8 to 2.9*10^{-8} erg cm^{-2} s^{-1} while the relative flux and contribution of the hot medium globally decreased. Reprocessing in the disc was likely to be strong at the end of our observations. The source showed a behaviour similar to that of previous outbursts, with some small deviations in the hard X-rays parameters' evolution. The radio, NIR and optical emission from jets was detected, and seen to fade as the source softened. The results are discussed within the context of disc and jet models.
