Abstract The study of galactic X-ray binaries (XRBs) has matured very rapidly in the past few years: RXTE has allowed us to observe, for the first time, phenomena that take place at the inner edge of the accretion discs that feed the central black hole or neutron star in these systems; Chandra and XMM-Newton are producing energy spectra of unprecedented quality for some of these objects; systematic studies at radio wavelengths are beginning to show that jets are quite a common phenomenon in XRBs. In short, this new era has produced several exciting discoveries, but it has also posed new and more sophisticated questions than could have been formulated 2-3 years ago. These motivate us to propose an ambitious program using INTEGRAL in combination with radio and softer X-ray observations (both spectral and timing) of a group of persistent, hard-spectra, low-mass X-ray binaries. We will probe the relation between radio and (non-thermal) hard X-ray emission in XRBs; this will eventually allow us to understand the physics of the mechanism that produces the hard X-rays, and its relation to the relativistic jets seen in several of these sources. We will measure their energy spectra over a very large frequency baseline, which we will use to address the issue of the relation between X-ray and bolometric luminosities, and their correlation to mass accretion rate. We anticipate the contributions of INTEGRAL to be part of the foundations of this important field.

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.
