Abstract We propose INTEGRAL observations of two bright low mass X-ray binaries,GX 17+2 and GX 13+1, with an exposuretime of 300 ks. These observations will be part ofa campaign of coordinated multiwavelength observationsin the radio, optical/IR, X-ray, and$\gamma$-ray bands. This project is specifically aimed at studyingthe recently discovered hard power-law tails in luminous Z sourcesand their correlation with ``inferred mass accretion rate(as defined by the position on the X-ray color--color diagram) andother source properties.These high-energy tails seem to be present (or more prominent) at low inferredaccretion rates, i.e.\ at periods of maximum radio emission from thesesources. We plan to directly probe this correlation between radio emission(probably due to jets) and hard tails, which might indicate jets as theorigin of hard components in luminous Z sources.This proposal was already accepted in the INTEGRAL AO2 in B priority;however, the observation could not be performed.

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.
