No model-independent evidence for a peak in binary black hole spin (mis)alignments
Noah E. Wolfe, Salvatore Vitale, Michael Zevin
The degree of black-hole spin-orbit misalignment ("tilts") in the astrophysical population could be a powerful diagnostic to distinguish between binary formation in isolation, in d…
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…
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…
Studying the gravitational-wave population without looking that FAR out
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,…
Gravitational wave signals from primordial black holes orbiting solar-type stars
Vitorio A. De Lorenci, David I. Kaiser, Patrick Peter +2
Primordial black holes (PBHs) with masses between and kg are candidates to contribute a substantial fraction of the total dark matter abundance. When in orbit 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…
