In this paper, a fast and parallelizable method based on Gaussian Processes (GPs) is introduced to emulate computer models that simulate the formation of binary black holes (BBHs) through the evolution of pairs of massive stars. Two obstacles that arise in this application are the a priori unknown conditions of BBH formation and the large scale of the simulation data. We address them by proposing a local emulator which combines a GP classifier and a GP regression model. The resulting emulator… 


Accuracy of inference on the physics of binary evolution from gravitational-wave observations
The properties of the population of merging binary black holes encode some of the uncertain physics of the evolution of massive stars in binaries. The binary black hole merger rate and chirp mass
Computer Model Calibration Using High-Dimensional Output
This work focuses on combining observations from field experiments with detailed computer simulations of a physical process to carry out statistical inference, and makes use of basis representations to reduce the dimensionality of the problem and speed up the computations required for exploring the posterior distribution.
stroopwafel: simulating rare outcomes from astrophysical populations, with application to gravitational-wave sources★
Gravitational-wave observations of double compact object (DCO) mergers are providing new insights into the physics of massive stars and the evolution of binary systems. Making the most of expected
Mining gravitational-wave catalogs to understand binary stellar evolution: A new hierarchical Bayesian framework
A novel technique that mines gravitational-wave catalogs to directly infer posterior probability distributions of the hyper-parameters describing formation and evolutionary scenarios to extract the underlying astrophysical origins of systems detected by LIGO and Virgo is explored.
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.
Exploring the Parameter Space of Compact Binary Population Synthesis
Abstract As we enter the era of gravitational wave astronomy, we are beginning to collect observations which will enable us to explore aspects of astrophysics of massive stellar binaries which were
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 perform
dart_board: Binary Population Synthesis with Markov Chain Monte Carlo
This work describes the publicly available code dart_board, which combines rapid binary evolution codes, typically used in traditional BPS, with modern Markov chain Monte Carlo methods, and takes a novel approach that treats the initial binary parameters and the supernova kick vector as model parameters.
The effect of the metallicity-specific star formation history on double compact object mergers
We investigate the impact of uncertainty in the metallicity-specific star formation rate over cosmic time on predictions of the rates and masses of double compact object mergers observable through
Efficient emulators of computer experiments using compactly supported correlation functions, with an application to cosmology
This work proposes a new model that uses a combination of low-order regression terms and compactly supported correlation functions to recreate the desired predictive behavior of the emulator at a fraction of the computational cost.
