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 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 Compact Supermassive Binary Black Hole System
We report on the discovery of a supermassive binary black hole system in the radio galaxy 0402+379, with a projected separation between the two black holes of just 7.3 pc. This is the closest black hole pair yet found by more than two orders of magnitude. These results are based upon recent multi-frequency observations using the Very Long Baseline Array (VLBA) which reveal two compact, variable...
متن کاملThe spin-flip phenomenon in 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 with candidate galaxies close to a binary black hole merger. In this paper we identify the typical mass ratio of the two black holes but then show that the distance when gravitational radiation becomes the dominant dissipative effect (over dynamica...
متن کاملConstraining the properties of the proposed supermassive black hole system in 3c66b: Limits from pulsar timing
Data from long term timing observations of the radio pulsar PSR B1855+09 have been searched for the signature of gravitational waves (G-waves) emitted by the proposed supermassive binary black hole system in 3C66B. For the case of a circular orbit, the emitted G-waves would generate detectable fluctuations in the pulse arrival times of PSR B1855+09. General expressions for the expected timing r...
