Establishing Compactness as a Population Observable in Gravitational-Wave Astronomy
Shrobana Ghosh, Charlie Hoy, Mark Hannam +1
Classically, black holes (BHs) are the most compact objects predicted in nature with C=0.5 in the Schwarzschild limit; C is defined as the mass-to-radius ratio in geometric units.…
Compactness Inference in Gravitational-Wave Mergers with PhenomDECO: Catalog Benchmarks and Robustness Diagnostics
Shrobana Ghosh, Charlie Hoy, Mark Hannam +1
Several gravitational wave (GW) observations have been identified as binary black hole (BBH) mergers, including systems with component masses that challenge typical formation scena…
A parametric signal plus noise inference framework for short duration non-Gaussian noise transients
Charlie Hoy, Ruxandra Bondarescu, Andrew Lundgren +1
Gravitational waves are now routinely detected with ground-based observatories, and, through a process known as Bayesian inference, their source properties are inferred. However, t…
The impact of precession and higher-order multipoles for gravitational wave cosmological inference
Charlie Hoy, Konstantin Leyde
Gravitational-wave astronomy presents an exciting opportunity to provide an independent measurement of the expansion rate of the Universe. By combining inferences for the binary co…
Inference with finite time series II: the window strikes back
Colm Talbot, Sylvia Biscoveanu, Aaron Zimmerman +9
Smooth window functions are often applied to strain data when inferring the parameters describing the astrophysical sources of gravitational-wave transients. Within the LIGO-Virgo-…
On the use and interpretation of signal-model indistinguishability measures for gravitational-wave astronomy
Jonathan E. Thompson, Charlie Hoy, Edward Fauchon-Jones +1
The difference ("mismatch") between two gravitational-wave (GW) signals is often used to estimate the signal-to-noise ratio (SNR) at which they will be distinguishable in a measure…
Waging a Campaign: Results from an Injection-Recovery Study involving 35 numerical Relativity Simulations and three Waveform Models
Sarp Akçay, Charlie Hoy, Jake Mac Uilliam
We present Bayesian inference results from an extensive injection-recovery campaign to test the validity of three state of the art quasicircular gravitational waveform models: \tex…
Incorporation of model accuracy in gravitational wave Bayesian inference
Charlie Hoy, Sarp Akcay, Jake Mac Uilliam +1
Inferring the properties of colliding black holes from gravitational-wave observations is subject to systematic errors arising from modelling uncertainties. Although the accuracy o…
Rarity of precession and higher-order multipoles in gravitational waves from merging binary black holes
Charlie Hoy, Stephen Fairhurst, Ilya Mandel
The latest binary black hole population estimates argue for a subpopulation of unequal component mass binaries with spins that are likely small but isotropically distributed. This…
