Gravitational-wave detections are enabling measurements of the rate of coalescences of
binaries composed of two compact objects—neutron stars and/or black holes. The …

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 …

Population-synthesis codes are an unique tool to explore the parameter space of massive
binary star evolution and binary compact object (BCO) formation. Most population-synthesis …

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

We have simulated the collapse and evolution of the core of a solar-metallicity 40 M⊙ star
and find that it explodes vigorously by the neutrino mechanism, despite its very high" …

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 …

In preparation for the release of the astrometric orbits of Gaia, Shahaf et al. proposed a
triage technique to identify astrometric binaries with compact companions based on their …

ABSTRACT Population III (Pop. III) binary stars likely produced the first stellar-born binary
black hole (BBH) mergers in the Universe. Here, we quantify the main sources of uncertainty …

Natal kicks are a matter of debate and they significantly affect the merger rate density of
compact objects. Here, we present a new simple formalism for natal kicks of neutron stars …

The component black holes (BHs) observed in gravitational-wave (GW) binary black hole
(BBH) events tend to be more massive and slower spinning than those observed in black …
