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 …

Galactic outflows are ubiquitous in galaxies containing active star formation or supermassive
black hole activity. The presence of a large-scale outflow from the center of our own Galaxy …

The astrophysical origin of gravitational wave (GW) events discovered by LIGO/VIRGO
remains an outstanding puzzle. In active galactic nuclei (AGNs), compact-object binaries …

We propose that the recently observed quasi-periodic eruptions (QPEs) in galactic nuclei
are produced by unstable mass transfer due to Roche lobe overflow of a low-mass main …

Black hole (BH) mergers detectable with the Laser Interferometer Gravitational-wave
Observatory (LIGO) can occur in active galactic nucleus (AGN) disks. Here we parameterize …

The origins of the stellar-mass black hole mergers discovered by LIGO/Virgo are still
unknown. Here we show that if migration traps develop in the accretion disks of active …

We present a directed search for continuous gravitational wave (CW) signals emitted by
spinning neutron stars located in the inner parsecs of the Galactic Center (GC). Compelling …

We investigate the formation of intermediate mass black holes (IMBHs) through hierarchical
mergers of stellar origin black holes (BHs), as well as BH mergers formed dynamically in …

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 …
