Dimensionally Reduced Waveforms for Spin-Induced Quadrupole Searches
Horng Sheng Chia, Thomas D. P. Edwards, Richard N. George +5
We present highly accurate, dimensionally-reduced gravitational waveforms for binary inspirals whose components have large spin-induced quadrupole moments. The spin-induced quadrup…
Success of the small mass ratio approximation during the final orbits of binary black hole simulations
Sergi Navarro Albalat, Aaron Zimmerman, Matthew Giesler +1
Recent studies have shown the surprising effectiveness of the small mass-ratio approximation (SMR) in modeling the relativistic two-body problem even at comparable masses. Up to no…
An approach to computing spectral shifts for black holes beyond Kerr
Asad Hussain, Aaron Zimmerman
Recent measurements of gravitational-wave ringdown following the merger of binary black holes raise the prospect of precision black hole spectroscopy in the near future. To perform…
Redshift factor and the small mass-ratio limit in binary black hole simulations
Sergi Navarro Albalat, Aaron Zimmerman, Matthew Giesler +1
We present a calculation of the Detweiler redshift factor in binary black hole simulations based on its relation to the surface gravity. The redshift factor has far-reaching applic…
A stochastic Stein Variational Newton method
Alex Leviyev, Joshua Chen, Yifei Wang +2
Stein variational gradient descent (SVGD) is a general-purpose optimization-based sampling algorithm that has recently exploded in popularity, but is limited by two issues: it is k…

Contents: APS April Meeting, by Aaron Zimmerman; Cosmic Explorer, the Next Exploration Step, by Varun Srivastava, Kathryne J. Daniel, and Stefan Ballmer
Efficient Gravitational Wave Template Bank Generation with Differentiable Waveforms
Adam Coogan, Thomas D. P. Edwards, Horng Sheng Chia +6
The most sensitive search pipelines for gravitational waves from compact binary mergers use matched filters to extract signals from the noisy data stream coming from gravitational…
