The coalescence of massive black hole (MBH) binaries following galaxy mergersis one of the main sources of low-frequency gravitational radiation. Ahigher-order relativistic phenomenon, the recoil as a result of the non-zeronet linear momentum carried away by gravitational waves, may have interestingconsequences for the demography of MBHs at the centers of galaxies. We studythe dynamics of recoiling MBHs and its observational consequences. The``gravitational rocket'' may: i) deplete MBHs from late-type spirals, dwarfgalaxies, and stellar clusters; ii) produce off-nuclear quasars, includingunusual radio morphologies during the recoil of a radio-loud source; and iii)give rise to a population of interstellar and intergalactic MBHs.Comment: emulateapj, 5 pages, 2 figures, to appear in the ApJ Letter
