Abstract One of the most active areas in black hole research currently is understanding the role of jets in the overall emission properties of black holes, from radio all the way to gamma-rays. Thanks to RXTE and the daily monitoring campaigns of radio and optical/IR facilities, we have gained good understanding of the relation between jet emission in the optical/Infrared (OIR), Radio and X-rays in the PCA band. Yet, our understanding about jet and high energy emission is still not clear because of limited information from INTEGRAL and due to absence of dedicated, reasonably long observations to investigate this relation directly. Using HEXTE on RXTE, and some INTEGRAL data we clearly see the spectral breaks right before we see evidence of compact jets in radio and IR during outburst decays, but we do not know how they evolve. This evolution may provide information about the conditions of launching compact jets that are ubiquitous in the low hard state of black holes. With the experience our group gained over the years, we can pinpoint almost exactly the time that the compact jet forms and evolves during decays of outbursts. We therefore propose one TOO observation of a GBHT with INTEGRAL for 220 ks at the transition to the hard state as the jet turns on to investigate the relation between the X-ray emission and jet formation. We will achieve multiwavelength coverage using ATCA in radio and SMARTS in OIR. This proposal is accompanied by an accepted SWIFT proposal. The current archival data are not enough to carry out this research.

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.
