Learning orbital dynamics of binary black hole systems from gravitational wave measurements
We introduce a gravitational waveform inversion strategy that discovers mechanical models of binary black hole (BBH) systems.
Genetic-algorithm-optimized neural networks for gravitational wave classification
Gravitational-wave detection strategies are based on a signal analysis technique known as matched filtering.
Surrogate models for precessing binary black hole simulations with unequal masses
The final black hole model, \RemnantModel, models the mass, spin, and recoil kick velocity of the remnant black hole.

The SXS Collaboration catalog of binary black hole simulations
Accurate models of gravitational waves from merging black holes are necessary for detectors to observe as many events as possible while extracting the maximum science.

Surrogate model of hybridized numerical relativity binary black hole waveforms
We present NRHybSur3dq8, a surrogate model for hybridized nonprecessing numerical relativity waveforms, that is valid for the entire LIGO band (starting at $20~\text{Hz}$) for stellar mass binaries with total masses as low as $2. 25\, M_{\odot}$.

Constraining the parameters of GW150914 & GW170104 with numerical relativity surrogates
In this paper we demonstrate the viability of these surrogate models as reliable parameter estimation tools, and show that within a fully Bayesian framework surrogates can help us extract more information from gravitational wave observations than traditional models.

A Note on QR-Based Model Reduction: Algorithm, Software, and Gravitational Wave Applications
While the proper orthogonal decomposition (POD) is optimal under certain norms it's also expensive to compute.

A Numerical Relativity Waveform Surrogate Model for Generically Precessing Binary Black Hole Mergers
A generic, non-eccentric binary black hole (BBH) system emits gravitational waves (GWs) that are completely described by 7 intrinsic parameters: the black hole spin vectors and the ratio of their masses.

A Surrogate Model of Gravitational Waveforms from Numerical Relativity Simulations of Precessing Binary Black Hole Mergers
We present the first surrogate model for gravitational waveforms from the coalescence of precessing binary black holes.

Fast prediction and evaluation of gravitational waveforms using surrogate models
Our approach is based on three offline steps resulting in an accurate reduced-order model that can be used as a surrogate for the true/fiducial waveform family.
