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 …

A massive black hole resides in the center of most, perhaps all galaxies. The one in the
center of our home galaxy, the Milky Way, provides a uniquely accessible laboratory for …

We report the results of the first-epoch observation with the ACIS-I instrument on the
Chandra X-Ray Observatory of Sagittarius A*(Sgr A*), the compact radio source associated …

We report the definite spectroscopic identification of≃ 40 OB supergiants, giants, and main-
sequence stars in the central parsec of the Galaxy. Detection of their absorption lines has …

We report on 75 mas resolution, near-IR imaging spectroscopy within the central 30 lt-days
of the Galactic center, taken with the new adaptive optics–assisted integral-field …

We analyze deep near-IR adaptive optics imaging (taken with NAOS/CONICA on the Very
Large Telescope at the European Southern Observatory, Chile), as well as new proper …

We analyze star formation in the nuclei of nine Seyfert galaxies at spatial resolutions down
to 0.085'', corresponding to length scales of order 10 pc in most objects. Our data were taken …

We present high spatial resolution (5 farcs 1× 2 farcs 7) Owens Valley Radio Observatory
(OVRO) millimeter array observations of HCN (J= 1-0) and HCO+(J= 1-0) emission in the …

We examine the spectrum of diffuse emission detected in the 17'× 17'field around Sgr A*
during 625 ks of Chandra observations. The spectrum exhibits He-like and H-like lines from …

Context. How star formation proceeds in the Galactic Center is a debated question.
Addressing this question will help us understand the origin of the cluster of massive stars …
