Super-Resolution without High-Resolution Labels for Black Hole Simulations
Thomas Helfer, Thomas D. P. Edwards, Jessica Dafflon +2
Generating high-resolution simulations is key for advancing our understanding of one of the universe's most violent events: Black Hole mergers. However, generating Black Hole simul…
Birefringence tests of gravity with multi-messenger binaries
Macarena Lagos, Leah Jenks, Maximiliano Isi +7
Extensions to General Relativity (GR) allow the polarization of gravitational waves (GW) from astrophysical sources to suffer from amplitude and velocity birefringence, which respe…
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…
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…
Nonlinear effects in black hole ringdown
Mark Ho-Yeuk Cheung, Vishal Baibhav, Emanuele Berti +8
We report evidence for nonlinear modes in the ringdown stage of the gravitational waveform produced by the merger of two comparable-mass black holes. We consider both the coalescen…
GRChombo: An adaptable numerical relativity code for fundamental physics
Tomas Andrade, Llibert Areste Salo, Josu C. Aurrekoetxea +29
GRChombo is an open-source code for performing Numerical Relativity time evolutions, built on top of the publicly available Chombo software for the solution of PDEs. Whilst GRChomb…
The Missing Link in Gravitational-Wave Astronomy: Discoveries waiting in the decihertz range
Manuel Arca Sedda, Christopher P. L. Berry, Karan Jani +27
The gravitational-wave astronomical revolution began in 2015 with LIGO's observation of the coalescence of two stellar-mass black holes. Over the coming decades, ground-based detec…
