Dynamical pairing in gravitational wave populations
Fabio Antonini, Aleksandra Olejak, Isobel Romero-Shaw +1
Binary black holes formed dynamically in star clusters are often associated with nearly equal-mass pairing. We show that this expectation is incomplete. The more general prediction…
Joint population and strong-lensing inference for resolved gravitational-wave events probes the black-hole merger rate beyond the peak of star formation
Matthew Mould
Gravitational waves can be lensed by intervening potentials of various scales. Strong lensing leads to underestimated distances and overestimated masses, biasing astrophysical resu…
End-to-End Population Inference from Gravitational-Wave Strain using Transformers
Konstantin Leyde, Stephen R. Green, Maximilian Dax +3
The population of compact binaries encodes information about their astrophysical origins and the expansion of the universe. Hierarchical Bayesian methods infer these properties by…
Gravitational-wave astronomy requires population-informed parameter estimation
Matthew Mould, Rodrigo Tenorio, Davide Gerosa
Gravitational-wave events are interpreted in terms of Bayesian posteriors for their source properties inferred under unphysical reference priors. Though these parameter estimates a…
Variance of gravitational-wave populations
Alessia Corelli, Davide Gerosa, Matthew Mould +1
We quantify the impact of finite catalog size, or "catalog variance," on current gravitational-wave population analyses. The distribution of merging binary black holes is commonly…
Neural Bayesian updates to populations with growing gravitational-wave catalogs
Noah E. Wolfe, Matthew Mould, John Veitch +1
As gravitational-wave catalogs grow, they will become increasingly computationally expensive to analyze in their entirety, especially when inferring astrophysical source population…
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…
Simulation-calibrated Bayesian inference for progenitor properties of the microquasar SS 433
Nathan Steinle, Matthew Mould, Sarah Al-Humaikani +3
SS433 is one of the most extreme Galactic X-ray binaries, launching semi-relativistic jets and showing clear signs of super-critical accretion onto what is likely a black hole.…
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,…
Evidence of the pair instability gap from black hole masses
Hui Tong, Maya Fishbach, Eric Thrane +13
Stellar theory predicts a forbidden range of black-hole masses between -- due to pair-instability supernovae, but evidence for such a gap in the mass distri…
Comparing astrophysical models to gravitational-wave data in the observable space
Alexandre Toubiana, Davide Gerosa, Matthew Mould +9
Comparing population-synthesis models to the results of hierarchical Bayesian inference in gravitational-wave astronomy requires a careful understanding of the domain of validity o…
Black Hole - Neutron Star and Binary Neutron Star Mergers from Population III and II stars
Benedetta Mestichelli, Michela Mapelli, Filippo Santoliquido +9
Population III (Pop.III) stars are expected to be massive and to undergo minimal mass loss due to their lack of metals, making them ideal progenitors of black holes and neutron…
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…

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…
Reconstructing parametric gravitational-wave population fits from non-parametric results without refitting the data
Cecilia Maria Fabbri, Davide Gerosa, Alessandro Santini +3
Combining multiple events into population analyses is a cornerstone of gravitational-wave astronomy. A critical component of such studies is the assumed population model, which can…
Which is which? Identification of the two compact objects in gravitational-wave binaries
Davide Gerosa, Viola De Renzis, Federica Tettoni +3
Compact objects observed in gravitational-wave astronomy so far always come in pairs and never individually. Identifying the two components of a binary system is a delicate operati…
Nonparametric analysis of correlations in the binary black hole population with LIGO-Virgo-KAGRA data
Jack Heinzel, Matthew Mould, Salvatore Vitale
