We explore chemically homogeneous evolution (CHE) as a formation channel for massive merging binary black holes (BBHs). We develop methods to include CHE in a rapid binary population synthesis code, Compact Object Mergers: Population Astrophysics and Statistics (COMPAS), which combines realistic models of binary evolution with cosmological models of the star-formation history of the Universe. For the first time, we simultaneously explore conventional isolated binary star evolution under the… Expand

These are exciting times for binary black hole (BBH) research. LIGO and Virgo detections are progressively drawing a spectacular fresco of BBH masses, spins and merger rates. In this review, weExpand
Detailed evolutionary models of massive contact binaries – I. Model grids and synthetic populations for the Magellanic Clouds
The majority of close massive binary stars with initial periods of a few days experience a contact phase, in which both stars overflow their Roche lobes simultaneously. We perform the firstExpand
Rates of Compact Object Coalescences
Gravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects – neutron stars and/or black holes. The coalescence rate of binariesExpand
Building Better Spin Models for Merging Binary Black Holes: Evidence for Nonspinning and Rapidly Spinning Nearly Aligned Subpopulations
Recent work paints a conflicting portrait of the distribution of black hole spins in merging binaries measured with gravitational waves. Some analyses find that a significant fraction of mergingExpand
Massive Stellar Triples Leading to Sequential Binary Black Hole Mergers in the Field
Stellar triples with massive stellar components are common and can lead to sequential binary black hole mergers. Here we outline the evolution toward these sequential mergers and explore these eventsExpand
Targeted Modeling of GW150914's Binary Black Hole Source with Dart_board
We present a new method to extract statistical constraints on the progenitor properties and formation channels of individual gravitational-wave sources. Although many different models have beenExpand


The chemically homogeneous evolutionary channel for binary black hole mergers: rates and properties of gravitational-wave events detectable by advanced LIGO
We explore the predictions for detectable gravitational-wave signals from merging binary black holes formed through chemically homogeneous evolution in massive short-period stellar binaries. We findExpand
Merging binary black holes formed through chemically homogeneous evolution in short-period stellar binaries
We explore a newly proposed channel to create binary black holes of stellar origin. This scenario applies to massive, tight binaries where mixing induced by rotation and tides transports the productsExpand
A new route towards merging massive black holes
Recent advances in gravitational-wave astronomy make the direct detection of gravitational waves from the merger of two stellar-mass compact objects a realistic prospect. Evolutionary scenariosExpand
Formation of the first three gravitational-wave observations through isolated binary evolution
The rapid binary population synthesis code COMPAS is used to show that all three events can be explained by a single evolutionary channel—classical isolated binary evolution via mass transfer including a common envelope phase. Expand
Evolution of binary stars and the effect of tides on binary populations
We present a rapid binary-evolution algorithm that enables modelling of even the most complex binary systems. In addition to all aspects of single-star evolution, features such as mass transfer, massExpand
On the formation history of Galactic double neutron stars
Double neutron stars (DNSs) have been observed as Galactic radio pulsars, and the recent discovery of gravitational waves from the DNS merger GW170817 adds to the known DNS population. We performExpand
Massive star evolution in close binaries:conditions for homogeneous chemical evolution
We investigate the impact of tidal interactions, before any mass transfer, on various properties of the stellar models. We study the conditions for obtaining homogeneous evolution triggered by tidalExpand
Binary Black Hole Mergers from Globular Clusters: Implications for Advanced LIGO.
This Letter studies the formation of black hole binaries in an extensive collection of realistic globular cluster models and finds that the mergers of dynamically formed binaries could be detected at a rate of ∼100 per year, potentially dominating the binary black hole merger rate. Expand
Black hole mergers and blue stragglers from hierarchical triples formed in globular clusters
Hierarchical triple-star systems are expected to form frequently via close binary-binary encounters in the dense cores of globular clusters. In a sufficiently inclined triple, gravitationalExpand
Which massive stars are gamma-ray burst progenitors?
The collapsar model for gamma-ray bursts requires three essential ingredients: a massive core, removal of the hydro- gen envelope, and enough angular momentum in the core. We study current massiveExpand
