Recalibrating Gravitational Wave Phenomenological Waveform Model
Kelvin K. H. Lam, Kaze W. K. Wong, Thomas D. P. Edwards
We investigate the possibility of improving the accuracy of the phenomenological waveform model, IMRPhenomD, by jointly optimizing all the calibration coefficients at once, given a…
Equivariant geometric convolutions for emulation of dynamical systems
Wilson G. Gregory, David W. Hogg, Ben Blum-Smith +3
Machine learning methods are increasingly being employed as surrogate models in place of computationally expensive and slow numerical integrators for a bevy of applications in the…
Constraining gravitational wave amplitude birefringence with GWTC-3
Thomas C. K. Ng, Maximiliano Isi, Kaze W. K. Wong +1
The propagation of gravitational waves can reveal fundamental features of the structure of spacetime. For instance, differences in the propagation of gravitational-wave polarizatio…
Fast gravitational wave parameter estimation without compromises
Kaze W. K. Wong, Maximiliano Isi, Thomas D. P. Edwards
We present a lightweight, flexible, and high-performance framework for inferring the properties of gravitational-wave events. By combining likelihood heterodyning, automatically-di…
ripple: Differentiable and Hardware-Accelerated Waveforms for Gravitational Wave Data Analysis
Thomas D. P. Edwards, Kaze W. K. Wong, Kelvin K. H. Lam +4
We propose the use of automatic differentiation through the programming framework jax for accelerating a variety of analysis tasks throughout gravitational wave (GW) science. First…
