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 …

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 …

Since the 1960s, when the connection between quasar energetics and supermassive black
holes was first established, galactic nuclei have remained objects of intense interest to …

A star that approaches a supermassive black hole (SMBH) on a circular extreme mass ratio
inspiral (EMRI) can undergo Roche lobe overflow (RLOF), resulting in a phase of long-lived …

We present a large∼ 30''× 30''spectroscopic survey of the Galactic Center using the
SINFONI IFU at the VLT. Combining observations of the last two decades we compile …

We present new observations of the nuclear star cluster in the central parsec of the Galaxy
with the adaptive optics assisted, integral field spectrograph SINFONI on the ESO/VLT. Our …

Supernovae are thought to arise from two different physical processes. The cores of
massive, short-lived stars undergo gravitational core collapse and typically eject a few solar …

Most, if not all, stars in the field are born in binary configurations or higher multiplicity
systems. In dense stellar environment such as the Galactic Center (GC), many stars are …

Most galactic nuclei harbor a massive black hole (MBH), whose birth and evolution are
closely linked to those of its host galaxy. The unique conditions near the MBH—high velocity …
