Abstract This proposal is the continuation of our accepted Targets of Opportunity (ToO) on Galactic Black Hole (BH) transients. They sources appear sporadically as X-ray Novae (XN) and display complex spectra and fast time-variability properties. Witnessing their spectro-timing evolutions, hard tail and radio properties are crucial to get clues on the accretion/ejection processes occurring in their vicinity. One possible approach is to use INTEGRAL together with ground-based facilities operating in radio/optical/Infra-Red (IR) to study the evolutions and relations between disc, Compton medium and jets. With an unprecedented high-energy sensitivity even in a crowded sky region, INTEGRAL allow us to i) constrain thermal Comptonization vs hybrid models for the production of hard components; ii) shed light on the nature of the additional parameter to the accretion rate, suspected to drive state changes; iii) correlate high-energy spectral behaviours with the properties of Quasi-Periodic Oscillations seen by RXTE, for which we have accepted programs; iv) probe the connection between accretion disc instabilities, high-energy components and the formation of relativistic jets, to find out whether radio, IR, optical, non-thermal components and the gamma-ray events originate -as found in quasars- within the same shocked area, downstream the relativistic jet. Our multiwavelength recent results (Cadolle Bel et al. 2007, 2008, 2009; Prat et al. 2009a) prove the importance and feasibility of such campaigns. Therefore, in the framework of ToO observations, we aim to analyze INTEGRAL data of up to two (new or known) BHXN simultaneously with our accepted ground-based programs we can trigger at any time, as successfully performed in the past.

Mission Description The INTEGRAL (International Gamma-Ray Astrophysics Laboratory) mission, launched by the European Space Agency (ESA) on October 17, 2002, was designed to study high-energy phenomena in the universe. INTEGRAL was operating until february 2025 and it was equipped with three high-energy instruments: the Imager on Board the INTEGRAL Satellite (IBIS), the Spectrometer on INTEGRAL (SPI), and the JEM-X (Joint European Monitor for X-rays). Its Optical Monitoring Camera (OMC) provided optical V-band magnitude measurements, complementing the high-energy observations.
