Binary interactions lead to the formation of intriguing objects, such as compact binaries,
supernovae, gamma ray bursts, X-ray binaries, pulsars, novae, cataclysmic variables, hot …

We describe the observation of GW170104, a gravitational-wave signal produced by the
coalescence of a pair of stellar-mass black holes. The signal was measured on January 4 …

All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported following the O1/O2
runs have near-zero effective spins. There are only three potential explanations for this. If the …

Studying the formation and evolution of black hole binaries (BHBs) is essential for the
interpretation of current and forthcoming gravitational wave (GW) detections. We investigate …

Abstract Compact Object Mergers: Population Astrophysics and Statistics (COMPAS;
https://compas. science) is a public rapid binary population synthesis code. COMPAS …

Upcoming observational runs of the LIGO-Virgo-KAGRA Collaboration and future
gravitational-wave (GW) detectors on the ground and in space require waveform models …

Gaia BH1, the first quiescent black hole (BH) detected from Gaia data, poses a challenge to
most binary evolution models: its current mass ratio is≈ 0.1, and its orbital period seems to …

The cosmic merger rate density of black hole binaries (BHBs) can give us an essential clue
to constraining the formation channels of BHBs, in light of current and forthcoming …

We present the merger rate density of Population III binary black holes (BHs) by means of a
widely used binary population synthesis code BSE with extensions to very massive and …
