Massive black hole binaries (MBHBs) represent an unavoidable outcome of hierarchical galaxy formation, but their dynamical evolution at sub-parsec scales is poorly understood, due to a combination of uncertainties in theoretical models and lack of firm observational evidence. In gas rich environments, it has been shown that a putative extended, steady circumbinary gaseous disc plays an important role in the MBHB evolution, facilitating its coalescence. How gas on galactic scales is transported… 
Accretion of clumpy cold gas onto massive black hole binaries: a possible fast route to binary coalescence
In currently favoured hierarchical cosmologies, the formation of massive black hole binaries (MBHBs) following galaxy mergers is unavoidable. Still, due the complex physics governing the
The effect of AGN feedback on the migration time-scale of supermassive black holes binaries
The gravitational interaction at parsec to sub-parsec scales between a circumbinary gas disc and a super massive black hole binary (SMBHB) is a promising mechanism to drive the migration of SMBHBs
Mass from a third star: transformations of close compact-object binaries within hierarchical triples
Close-orbit binaries consisting of two compact objects are a center of attention because of the detection of gravitational-radiation-induced mergers. The creation of close, compact-object binaries

Infalling clouds on to supermassive black hole binaries - I. Formation of discs, accretion and gas dynamics
There is compelling evidence that most -if not all- galaxies harbour a super-massive black hole (SMBH) at their nucleus, hence binaries of these massive objects are an inevitable product of the
Infalling clouds on to supermassive black hole binaries - II. Binary evolution and the final parsec problem
The formation of massive black hole binaries (MBHBs) is an unavoidable outcome of galaxy evolution via successive mergers. However, the mechanism that drives their orbital evolution from parsec
Cold, clumpy accretion onto an active supermassive black hole.
TLDR
Observations reveal a cold, clumpy accretion flow towards a supermassive black hole fuel reservoir in the nucleus of the Abell 2597 Brightest Cluster Galaxy, a nearby giant elliptical galaxy surrounded by a dense halo of hot plasma.
Tidal Disruptions in Circumbinary Disks. I. Star Formation, Dynamics, and Binary Evolution
In our current interpretation of the hierarchical structure of the universe, it is well established that galaxies collide and merge with each other during their lifetimes. If massive black holes
The Assembly and Merging History of Supermassive Black Holes in Hierarchical Models of Galaxy Formation
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
Formation of supermassive black holes
Evidence shows that massive black holes reside in most local galaxies. Studies have also established a number of relations between the MBH mass and properties of the host galaxy such as bulge mass
Massive Black Hole Binary Evolution
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
Eccentricity of Supermassive Black Hole Binaries Coalescing from Gas-rich Mergers
Angular momentum loss to circumbinary gas provides a possible mechanism for overcoming the "last parsec" problem and allowing the most massive black hole binaries formed from galactic mergers to
THE POPULATION OF VISCOSITY- AND GRAVITATIONAL WAVE-DRIVEN SUPERMASSIVE BLACK HOLE BINARIES AMONG LUMINOUS ACTIVE GALACTIC NUCLEI
Supermassive black hole binaries (SMBHBs) in galactic nuclei are thought to be a common by-product of major galaxy mergers. We use simple disk models for the circumbinary gas and for the binary-disk
