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 …

The Galactic Center is an excellent laboratory for studying phenomena and physical
processes that may be occurring in many other galactic nuclei. The center of our Milky Way …

Abstract The Laser Interferometer Gravitational-wave Observatory (LIGO) found direct
evidence for double black hole binaries emitting gravitational waves. Galactic nuclei are …

Rates of stellar tidal disruption events (TDEs) by supermassive black holes (SMBHs) due to
two-body relaxation are calculated using a large galaxy sample (N≈ 200) in order to …

We present the results of 16 years of monitoring stellar orbits around the massive black hole
in the center of the Milky Way, using high-resolution near-infrared techniques. This work …

The environment near supermassive black holes (SMBHs) in galactic nuclei contains a large
number of stars and compact objects. A fraction of these are likely to be members of …

Nuclear star clusters surrounding supermassive black holes (SMBHs) in galactic nuclei
contain large numbers of stars, black holes (BHs), and neutron stars (NSs), a fraction of …

We use multiscale smoothed particle hydrodynamic simulations to study the inflow of gas
from galactic scales (∼ 10 kpc) down to≲ 0.1 pc, at which point the gas begins to resemble …

The supermassive black hole at the center of the Milky Way plays host to a massive, young
cluster that may have formed in one of the most inhospitable environments in the Galaxy. We …

A star that wanders too close to a massive black hole (BH) is shredded by the BH's tidal
gravity. Stellar gas falls back to the BH at a rate initially exceeding the Eddington rate …
