The gravitational wave detectors have shown a population of massive black holes that do
not resemble those observed in the Milky Way,–and whose origin is debated,–. According to …

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 …

The accretion disks of active galactic nuclei (AGNs) are promising locations for the merger of
compact objects detected by gravitational wave (GW) observatories. Embedded within a …

Measurement of spin-precession in black hole binary mergers observed with gravitational
waves is an exciting milestone as it relates to both general relativistic dynamics and …

Data from ground-based gravitational-wave detectors contains numerous short-duration
instrumental artifacts, called'glitches'. The high rate of these artifacts in turn results in a …

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

Resolving the formation channel (s) of merging binary black holes is a key goal in
gravitational-wave astronomy. The orbital eccentricity is believed to be a precious tracer of …

Complete waveform models able to account for arbitrary nonplanar orbits represent a holy
grail in current gravitational-wave astronomy. Here, we take a step toward this direction and …

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

Gravitational-wave signals from binaries that contain spinning black holes in general include
an asymmetry between the+ m and-m multipoles that is not included in most signal models …
