Reversible-jump MCMC reveals binary black hole subpopulations with distinct redshift evolution
April Qiu Cheng, Alexandre Toubiana, Sylvia Biscoveanu +1
Analyses of the growing catalog of binary black hole (BBH) mergers observed by the LIGO-Virgo-KAGRA detectors are beginning to resolve features in their population-level mass, spin…

A unified harmonic framework for dark siren cosmology
April Qiu Cheng, Jonathan Gair
The galaxy catalog dark siren method aims to infer cosmological parameters from gravitational waves (GWs) without an electromagnetic counterpart by statistically marginalizing over…

Exploring selection biases in FRB dispersion-galaxy cross-correlations with magnetohydrodynamical simulations
April Qiu Cheng, Shion Elizabeth Andrew, Haochen Wang +1
The dispersion measure (DM) of fast radio bursts (FRBs) in conjunction with their redshifts can be used as powerful probes of the distribution of extragalactic plasma. With a large…
