Spinformation: do gravitational-wave events carry information beyond effective spins?
Cailin Plunkett, Jack Heinzel, Noah E. Wolfe +2
While the spin vectors of binary black holes offer insight into the astrophysical formation channels of these systems, individual spins are less precisely measured through gravitat…
Binary-black hole spin population results may be driven by prior degeneracies
Noah E. Wolfe, Asad Hussain, Jack Heinzel +1
Gravitational waves carry information on the spins of merging binary-black holes. The orientations of their spins relative to their orbits ("tilts")---while challenging to measure-…
Measurement prospects for the pair-instability mass cutoff with gravitational waves
Matthew Mould, Jack Heinzel, Sofia Alvarez-Lopez +3
Pair-instability supernovae leave behind no compact remnants, resulting in a predicted gap in the distribution of stellar black-hole masses. Gravitational waves from binary black-h…
Reducing systematic uncertainties in gravitational-wave population analyses by increasing the detection threshold
Noah E. Wolfe, Matthew Mould, Jack Heinzel +1
From catalogs of gravitational-wave transients, the population-level properties of their sources and the formation channels of merging compact binaries can be constrained. However,…
When (not) to trust Monte Carlo approximations for hierarchical Bayesian inference
Jack Heinzel, Salvatore Vitale
The coming years of gravitational wave astrophysics promises thousands of new detections, which can unlock fundamental scientific insights if the information in each observation ca…
Nowhere left to hide: revealing realistic gravitational-wave populations in high dimensions and high resolution with PixelPop
Sofia Alvarez-Lopez, Jack Heinzel, Matthew Mould +1
The origins of merging compact binaries observed by the LIGO-Virgo-KAGRA gravitational-wave detectors remain uncertain, with multiple astrophysical channels possibly contributing t…
The Long Road to Alignment: Measuring Black Hole Spin Orientation with Expanding Gravitational-Wave Datasets
Salvatore Vitale, Matthew Mould
Measuring the distribution of spin tilts-the angles between the spin vectors and the binary orbital angular momentum-in stellar-mass binary black holes detected by LIGO-Virgo-KAGRA…
Constraining Population III stellar demographics with next-generation gravitational-wave observatories
Cailin Plunkett, Matthew Mould, Salvatore Vitale
Next-generation gravitational-wave observatories will reach farther into the universe than currently possible, revealing black-hole mergers from early stellar binary systems such a…
Rapid inference and comparison of gravitational-wave population models with neural variational posteriors
Matthew Mould, Noah E. Wolfe, Salvatore Vitale
The LIGO-Virgo-KAGRA catalog has been analyzed with an abundance of different population models due to theoretical uncertainty in the formation of gravitational-wave sources. To ex…
Nonparametric analysis of correlations in the binary black hole population with LIGO-Virgo-KAGRA data
Jack Heinzel, Matthew Mould, Salvatore Vitale
Formation channels of merging compact binaries imprint themselves on the distributions and correlations of their source parameters, but current understanding of this population is…
PixelPop: High Resolution Nonparameteric Inference of Gravitational-Wave Populations in Multiple Dimensions
Jack Heinzel, Matthew Mould, Sofía Álvarez-López +1
The origins of merging compact binaries observed by gravitational-wave detectors remains highly uncertain. Several astrophysical channels may contribute to the overall merger rate,…
Probing Correlations in the Binary Black Hole Population with Flexible Models
Jack Heinzel, Sylvia Biscoveanu, Salvatore Vitale
The astrophysical formation channels of binary black hole systems predict correlations between their mass, spin, and redshift distributions, which can be probed with gravitational-…
Application of asymptotic expansions for maximum likelihood estimators' errors to gravitational waves from binary mergers: the network case
Salvatore Vitale, Michele Zanolin
This paper describes the most accurate analytical frequentist assessment to date of the uncertainties in the estimation of physical parameters from gravitational waves generated by…
