Abstract We propose a 600 ksec INTEGRAL observation of the gamma-ray blazar 3C 279 simultaneous with XMM-Newton and GLAST/LAT. The main goal is to measure its hard X-ray properties (spectrum, variability) in correlation to simultaneous high-energy observations at X- and gamma-ray energies, which are guaranteed by an approved XMM-Netwon proposal and by GLAST (assuming proper operation then). These high-energy data of unprecedented sensitivity and energy coverage will be supplemented by ground-based measurements, adding finally up to multifrequency spectra of unprecedented accuracy and spectral extent, i.e. up to hundreds of GeV. Such high-quality SEDs will provide severe constraints on their modelling and therefore have the potential to discriminate among emission models. Because the observed radiation of 3C 279 is almost purely of non-thermal origin, we are studying jet physics including the physics of particle acceleration.

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.
