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…
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…
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.…
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…
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…
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…
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,…
One to many: comparing single gravitational-wave events to astrophysical populations
Matthew Mould, Davide Gerosa, Marco Dall'Amico +1
Gravitational-wave observations have revealed sources whose unusual properties challenge our understanding of compact-binary formation. Inferring the formation processes that are b…
QLUSTER: quick clusters of merging binary black holes
Davide Gerosa, Matthew Mould
This short document illustrates QLUSTER: a toy model for populations of binary black holes in dense astrophysical environments. QLUSTER is a simple tool to investigate the occurren…
Precision Ephemerides for Gravitational-wave Searches -- IV: Corrected and refined ephemeris for Scorpius X-1
T. L. Killestein, M. Mould, D. Steeghs +3
Low-mass X-ray binaries have long been theorised as potential sources of continuous gravitational-wave radiation, yet there is no observational evidence from recent LIGO/Virgo obse…
Which black hole formed first? Mass-ratio reversal in massive binary stars from gravitational-wave data
Matthew Mould, Davide Gerosa, Floor S. Broekgaarden +1
Population inference of gravitational-wave catalogues is a useful tool to translate observations of black-hole mergers into constraints on compact-binary formation. Different forma…
Deep learning and Bayesian inference of gravitational-wave populations: Hierarchical black-hole mergers
Matthew Mould, Davide Gerosa, Stephen R. Taylor
The catalog of gravitational-wave events is growing, and so are our hopes of constraining the underlying astrophysics of stellar-mass black-hole mergers by inferring the distributi…
Gravitational-wave population inference at past time infinity
Matthew Mould, Davide Gerosa
Population studies of stellar-mass black-hole binaries have become major players in gravitational-wave astronomy. The underlying assumptions are that the targeted source parameters…
The mass gap, the spin gap, and the origin of merging binary black holes
Vishal Baibhav, Davide Gerosa, Emanuele Berti +3
Two of the dominant channels to produce the black-hole binary mergers observed by LIGO and Virgo are believed to be the isolated evolution of stellar binaries in the field and dyna…
