Abstract We propose four 80ksec observations of the black hole candidate Cyg X-1, simultaneous to our accepted XMM-Newton observations in the fall of 2004. The scientific aim of this campaign is to measure a high signal to noise spectrum of Cyg X-1 from 0.5 to above 600keV, allowing us to constrain models for the Comptonizing plasma responsible for the hard X-ray spectrum, to constrain the amount of Compton reflection in the system, to provide the >10keV continuum above a possibly relativistically broadened Fe Kalpha line, and to search for and study the effects of non-thermal Comptonization and/or synchrotron self-Compton emission from a jet.

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.
