Spin precession in merging black-hole binaries is a treasure trove for both astrophysics and fundamental physics. There are now well-established strategies to infer from gravitational-wave data whether at least one of the two black holes is precessing. In this paper we tackle the next-in-line target, namely the statistical assessment that the observed system has two precessing spins. We find that the recently developed generalization of the effective precession spin parameter χ p is a well-suited…

No Evidence that the Majority of Black Holes in Binaries Have Zero Spin

The spin properties of merging black holes observed with gravitational waves can offer novel information about the origin of these systems. The magnitudes and orientations of black hole spins offer a

Implementation of a generalized precession parameter in the RIFT parameter estimation algorithm

Since the initial discovery of gravitational waves in 2015, significant developments have been made towards waveform interpretation and estimation of compact binary source parameters. We present

Use of gravitational waves to probe the formation channels of compact binaries

With the discovery of the binary black hole coalescences GW150914 and GW151226, the era of gravitational-wave astrophysics has started. Gravitational-wave signals emitted by compact binary

Massive black hole binary inspiral and spin evolution in a cosmological framework

Massive black hole (MBH) binary inspiral time-scales are uncertain, and their spins are even more poorly constrained. Spin misalignment introduces asymmetry in the gravitational radiation, which

GW190521: Orbital Eccentricity and Signatures of Dynamical Formation in a Binary Black Hole Merger Signal

Pair-instability supernovae are thought to restrict the formation of black holes in the mass range ∼ 50 – 135 M ⊙ . However, black holes with masses within this “high mass gap” are expected to form

Hierarchical analysis of gravitational-wave measurements of binary black hole spin–orbit misalignments

Binary black holes may form both through isolated binary evolution and through dynamical interactions in dense stellar environments. The formation channel leaves an imprint on the alignment between

Bilby: A User-friendly Bayesian Inference Library for Gravitational-wave Astronomy

A user-friendly Bayesian inference library for gravitational-wave astronomy, Bilby, is introduced and an example in which the shape of the black hole mass distribution is inferred from an ensemble of observations of binary black hole mergers is provided.

Massively parallel Bayesian inference for transient gravitational-wave astronomy

This work investigates an accurate, flexible, and scalable method for astrophysical inference: parallelized nested sampling, which reduces the wall-time of inference scales almost linearly with the number of parallel processes running on a high-performance computing cluster.
