Coalescence of binary supermassive black holes (SBHs) would constitute the strongest sources of gravitational waves to be observed by LISA. While the formation of binary SBHs during galaxy mergers is almost inevitable, coalescence requires that the separation between binary components first drop by a few orders of magnitude, due presumably to interaction of the binary with stars and gas in a galactic nucleus. This article reviews the observational evidence for binary SBHs and discusses how they… 
Massive Binary Black Holes in Galactic Nuclei and Their Path to Coalescence
Massive binary black holes (105 M⊙–109 M⊙) form at the centre of galaxies that experience a merger episode. They are expected to coalesce into a larger black hole, following the emission of
Massive perturbers and the efficient merger of binary massive black holes
We show that dynamical relaxation in the aftermath of a galactic merger and the ensuing formation and decay of a binary massive black hole (MBH) are dominated by massive perturbers (MPs) such as
EFFICIENT MERGER OF BINARY SUPERMASSIVE BLACK HOLES IN MERGING GALAXIES
In spherical galaxies, binary supermassive black holes (SMBHs) have difficulty reaching sub-parsec separations due to depletion of stars on orbits that intersect the massive binary—the "final parsec
MERGERS OF UNEQUAL-MASS GALAXIES: SUPERMASSIVE BLACK HOLE BINARY EVOLUTION AND STRUCTURE OF MERGER REMNANTS
Galaxy centers are residing places for supermassive black holes (SMBHs). Galaxy mergers bring SMBHs close together to form gravitationally bound binary systems, which, if able to coalesce in less
Evolution of supermassive black hole binaries and tidal disruption rates in non-spherical galactic nuclei
Binary supermassive black holes (SMBH) are expected to form naturally during galaxy mergers. After the dynamical friction phase, when the two SMBHs become gravitationally bound to each other, and a
Dynamics of triple black hole systems in hierarchically merging massive galaxies
Galaxies with stellar bulges are generically observed to host supermassive black holes (SMBHs). The hierarchical merging of galaxies should therefore lead to the formation of SMBH binaries. Merging
Compact object mergers: observations of supermassive binary black holes and stellar tidal disruption events
Abstract The capture and disruption of stars by supermassive black holes (SMBHs), and the formation and coalescence of binaries, are inevitable consequences of the presence of SMBHs at the cores of
Nuclear Activity in Galaxies driven by Binary Supermassive Black Holes
Nuclear activity in galaxies is closely connected to galactic mergers and supermassive black holes (SBH). Galactic mergers perturb substantially the dynamics of gas and stellar population in the
Aspects of Supermassive Black Hole Growth in Nearby Active Galactic Nuclei
Super-massive black holes (SBHs) have long been identified as the engines of active galactic nuclei (AGNs) and are now considered to play a key role in galaxy evolution. In this dissertation I
Tidal Disruption of Stellar Objects by Hard Supermassive Black Hole Binaries
Supermassive black hole binaries (SMBHBs) are expected by the hierarchical galaxy formation model in ΛCDM cosmology. There is some evidence in the literature for SMBHBs in active galactic nuclei, but

Long-term evolution of massive black hole binaries. II. Binary evolution in low-density galaxies
We use direct-summation N-body integrations to follow the evolution of binary black holes at the centers of galaxy models with large, constant-density cores. Particle numbers as large as 0.4 × 106
Observational evidence for supermassive black hole binaries
Coalescing massive black hole binaries are powerful emitters of gravitational waves, in the LISA sensitivity range for masses MBH ≈ 104–7 M⊙. According to hierarchical galaxy merger models, binary
Evolution of massive binary black holes
ABSTRA C T Since many or most galaxies have central massive black holes (BHs), mergers of galaxies can form massive binary black holes (BBHs). In this paper we study the evolution of massive BBHs in
Binary pairs of supermassive black holes: formation in merging galaxies
A process in which supermassive binary blackholes are formed in nuclei of supergiant galaxies due to galaxy mergers is examined. There is growing evidence that mergers of galaxies are common and that
Single and binary black holes and their influe nce on nuclear structure
Massive central objects affect both the structure and evolution of galactic nuclei. Adiabatic growth of black holes generates power-law central density profiles with logarithmic slopes in the range

We assess models for the assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical buildup far up in the dark halo merger tree. Motivated by the recent

We investigate a hierarchical structure formation scenario in which galaxy stellar cores are created from the binding energy liberated by shrinking supermassive black hole (SMBH) binaries. The binary
Long-term evolution of massive black hole binaries.
The long-term evolution of massive black hole binaries at the centers of galaxies is studied in a variety of physical regimes, with the aim of resolving the “final parsec problem,” i.e. how black
Formation of Galactic Nuclei
