Gravitational waves provide a unique tool for observational astronomy. While the first LIGO--Virgo catalogue of gravitational-wave transients (GWTC-1) contains eleven signals from black hole and neutron star binaries, the number of observations is increasing rapidly as detector sensitivity improves. To extract information from the observed signals, it is imperative to have fast, flexible, and scalable inference techniques. In a previous paper, we introduced BILBY: a modular and user-friendly… Expand

Issues of mismodeling gravitational-wave data for parameter estimation
Bayesian inference is used to extract unknown parameters from gravitational-wave signals. Detector noise is typically modelled as stationary, although data from the LIGO and Virgo detectors is notExpand

Black-hole spectroscopy, the no-hair theorem, and GW150914: Kerr versus Occam

Confusing Head-On Collisions with Precessing Intermediate-Mass Binary Black Hole Mergers.
It is shown that in situations where standard parameter inference of compact binaries may report component masses inside (outside) the pair-instability supernova gap, the true object may be a head-on merger with masses outside (inside) this gap. Expand
