Supermassive black hole binary mergers
Massive merging black holes will be the primary sources of powerful gravitational waves at low frequency, and will permit to test General Relativity if we identify candidate galaxies that are close to a binary black hole merger. In this paper we show that for a typical range of mass ratios of the two black holes the final stage of the merger is preceded by a rapid precession and a subsequent sp...
متن کاملOrbital motion in the radio galaxy 3C 66B: evidence for a supermassive black hole binary.
Supermassive black hole binaries may exist in the centers of active galactic nuclei such as quasars and radio galaxies, and mergers between galaxies may result in the formation of supermassive binaries during the course of galactic evolution. Using the very-long-baseline interferometer, we imaged the radio galaxy 3C 66B at radio frequencies and found that the unresolved radio core of 3C 66B sho...
متن کاملSupermassive binary black hole mergers
When galaxies collide, dynamical friction drives their central supermassive black holes close enought to each other such that gravitational radiation becomes the leading dissipative effect. Gravitational radiation takes away energy, momentum and angular momentum from the compact binary, such that the black holes finally merge. In the process, the spin of the dominant black hole is reoriented. O...
متن کاملA supermassive binary black hole in the quasar 3 C 345
Radio loud active galactic nuclei present a remarkable variety of signs indicating the presence of periodical processes possibly originating in binary systems of supermassive black holes, in which orbital motion and precession are ultimately responsible for the observed broad-band emission variations, as well as for the morphological and kinematic properties of the radio emission on parsec scal...
متن کاملInfrared Time Lags for the Periodic Quasar Pg 1302 -
The optical light curve of the quasar PG 1302-102 at z = 0.278 shows a strong, smooth 5.2 yr periodic signal, detectable over a period of ∼ 20 yr. Although the interpretation of this phenomenon is still uncertain, the most plausible mechanisms involve a binary system of two supermassive black holes with a subparsec separation. At this close separation, the nuclear black holes in PG 1302-102 wil...
