Massive stars play a major role in the evolution of their host galaxies and serve as important
probes of the distant Universe. It has been established that the majority of massive stars …

We combine amortized neural posterior estimation with importance sampling for fast and
accurate gravitational-wave inference. We first generate a rapid proposal for the Bayesian …

Spin precession is one of the key physical effects that coul unveil the origin of the compact
binaries detected by ground-and space-based gravitational-wave (GW) detectors, and shed …

The growing population of compact binary mergers detected with gravitational waves
contains multiple events that are challenging to explain through isolated binary evolution …

Eccentricity and spin precession are key observables in gravitational-wave astronomy,
encoding precious information about the astrophysical formation of compact binaries …

The current and upcoming generations of gravitational wave experiments represent an
exciting step forward in terms of detector sensitivity and performance. For example, key …

The plunge-merger stage of the binary-black hole coalescence, when the bodies' velocities
reach a large fraction of the speed of light and the gravitational-wave luminosity peaks …

We investigate the formation of intermediate mass black holes (IMBHs) through hierarchical
mergers of stellar origin black holes (BHs), as well as BH mergers formed dynamically in …

We present IMRPhenomXODE, a new phenomenological frequency-domain waveform
approximant for gravitational wave (GW) signals from precessing binary black holes (BBHs) …

In this work we introduce phenomxo4a, the first phenomenological, frequency-domain
gravitational waveform model to incorporate multipole asymmetries and precession angles …
