Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

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 …

Most, if not all, galaxies harbor at their center a supermassive black hole (SMBH) that sculpts
the dynamics of objects inhabiting galactic nuclei. SMBH binaries (SMBHBs) are expected to …

Among the potential milliHz gravitational wave (GW) sources for the upcoming space-based
interferometer LISA are extreme-or intermediate-mass ratio inspirals (EMRI/IMRIs). These …

Coalescing supermassive black hole binaries (BHBs) are expected to be the loudest
sources of gravitational waves (GWs) in the Universe. Detection rates for ground or space …

The emission of gravitational waves (GWs) during single–single close encounters in galactic
nuclei (GNs) leads to the formation and rapid merger of highly eccentric stellar-mass black …

The gravitational wave (GW) signal from binary black hole (BBH) mergers is a promising
probe of Population III (Pop III) stars. To fully unleash the power of the GW probe, one …

ABSTRACT A tidal disruption event (TDE) occurs when a star is destroyed by the strong tidal
shear of a massive black hole (MBH). The accumulation of TDE observations over the last …

Close stellar binaries are prone to undergo a phase of stable mass transfer in which a star
loses mass to its companion. Assuming that the donor star loses mass along the …

In dense stellar clusters like galactic nuclei and globular clusters, stellar densities are so
high that stars might physically collide with each other. In galactic nuclei the energy and …
