The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

While most of the compact-binary mergers detected by LIGO and Virgo are expected to
consist of first-generation black holes formed from the collapse of stars, others might instead …

We analyze the population properties of black holes (BHs) and neutron stars (NSs) in
compact binary systems using data from the LIGO–Virgo Gravitational-Wave Transient …

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 …

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 …

LIGO and Virgo have reported the detection of GW190521, from the merger of a binary black
hole (BBH) with a total mass around 150 M⊙. While current stellar models limit the mass of …

We construct an inspiral-merger-ringdown eccentric gravitational-wave (GW) model for
binary black holes with non-precessing spins within the effective-one-body formalism. This …

In a star cluster with a sufficiently large escape velocity, black holes (BHs) that are produced
by BH mergers can be retained, dynamically form new BH binaries, and merge again. This …

The last decade of observational and theoretical developments in stellar and binary
evolution provides an opportunity to incorporate major improvements to the predictions from …

The unprecedented range of second-generation gravitational-wave (GW) observatories calls
for refining the predictions of potential sources and detection rates. The coalescence of …
