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 …

Gravitational waves (GW) emitted by merging black holes (BH) and neutron stars are now
routinely detected. Those are the afterlives of massive stars that formed all across the …

Most massive stars are members of a binary or a higher-order stellar system, where the
presence of a binary companion can decisively alter their evolution via binary interactions …

Gravitational-wave detectors are starting to reveal the redshift evolution of the binary black
hole (BBH) merger rate, R BBH (z). We make predictions for R BBH (z) as a function of black …

Gravitational-wave (GW) detections are starting to reveal features in the mass distribution of
double compact objects. The lower end of the black hole (BH) mass distribution is especially …

Making the most of the rapidly increasing population of gravitational-wave detections of
black hole (BH) and neutron star (NS) mergers requires comparing observations with …

Several features in the mass spectrum of merging binary black holes (BBHs) have been
identified using data from the Third Gravitational Wave Transient Catalog (GWTC-3). These …

We present realistic expectations for the number and properties of neutron star binary
mergers to be detected as multi-messenger sources during the upcoming fourth observing …

With the remarkable success of the Ligo-Virgo-Kagra consortium in detecting binary black
hole mergers, it has become possible to use the population properties to constrain our …
