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 …

Multi-dimensional fluid flow plays a paramount role in the explosions of massive stars as
core-collapse supernovae. In recent years, three-dimensional (3D) simulations of these …

We report on the population properties of compact binary mergers inferred from gravitational-
wave observations of these systems during the first three LIGO-Virgo observing runs. 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 …

We explore a newly proposed channel to create binary black holes of stellar origin. This
scenario applies to massive, tight binaries where mixing induced by rotation and tides …

Motivated by the recent detection of gravitational waves from the black hole binary merger
GW150914, we study the dynamical evolution of (stellar-mass) black holes in galactic nuclei …

Mergers of black hole–neutron star (BHNS) binaries have now been observed by
gravitational wave (GW) detectors with the recent announcement of GW200105 and …

The recent detections of the binary black hole mergers GW150914 and GW151226 have
inaugurated the field of gravitational-wave astronomy. For the two main formation channels …

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 …
