The effect of spin mismodeling on gravitational-wave measurements of the binary neutron star mass distribution
Sylvia Biscoveanu, Colm Talbot, Salvatore Vitale
The binary neutron star (BNS) mass distribution measured with gravitational-wave observations has the potential to reveal information about the dense matter equation of state, supe…
Building better spin models for merging binary black holes: Evidence for non-spinning and rapidly spinning nearly aligned sub-populations
Shanika Galaudage, Colm Talbot, Tushar Nagar +3
Recent work paints a conflicting portrait of the distribution of black hole spins in merging binaries measured with gravitational waves. Some analyses find that a significant fract…
Probing Extremal Gravitational-Wave Events with Coarse-Grained Likelihoods
Reed Essick, Amanda Farah, Shanika Galaudage +4
As catalogs of gravitational-wave transients grow, new records are set for the most extreme systems observed to date. The most massive observed black holes probe the physics of pai…
Bilby-MCMC: An MCMC sampler for gravitational-wave inference
Gregory Ashton, Colm Talbot
We introduce Bilby-MCMC, a Markov-Chain Monte-Carlo sampling algorithm tuned for the analysis of gravitational waves from merging compact objects. Bilby-MCMC provides a parallel-te…
Hierarchical Inference of Binary Neutron Star Mass Distribution and Equation of State with Gravitational Waves
Jacob Golomb, Colm Talbot
Gravitational wave observations of binary neutron star mergers provide valuable information about neutron star structure and the equation of state of dense nuclear matter. Numerous…
Inference with finite time series: Observing the gravitational Universe through windows
Colm Talbot, Eric Thrane, Sylvia Biscoveanu +1
Time series analysis is ubiquitous in many fields of science including gravitational-wave astronomy, where strain time series are analyzed to infer the nature of gravitational-wave…
