英文摘要	A large fraction of galactic nuclei is expected to host supermassive black hole binaries (BI LB), likely formed during the early phase of galaxies assembly and merging. In this paper, we use a large set of state-of-art numerical models to investigate the interplay between a BIM and a massive star cluster (GCs) driven toward the galactic centre by dynamical friction. Varying the BHB mass and mass ratio and the GC orbit, we show that the reciprocal feedback exerted between GCs and the BHB shapes their global properties. We show that, at GC-to-BHB mass ratios above 0.1, the GC affects notably the BHB orbital evolution, possibly boosting its coalescence. This effect is maximized if the GC moves on a retrograde orbit, and for a nonequal mass BHB. We show that the GC debris dispersed around the galactic nucleus can lead to the formation of a nuclear cluster, depending on the BHB tidal field, and that the distribution of compact remnants resulting from the GC disruption can carry information about the BHB orbital properties. We find that red giant stars delivered by the spiralling GC can be disrupted at a rate of similar or equal to (0.7 - 7) x 10(-7) yr(-1) for BHB masses similar to 10(7)M(circle dot), while tens to hundreds of stars can be possibly observed in the galactic halo as high-velocity stars, with velocities up to similar to 2000 km s(-1), depending on the BHB orbital properties.
