A Large-scale CO Imaging of the Galactic Center. II. Dynamical Properties of Molecular Clouds [PDF]
, 1998 The data from the Nobeyama Radio Observatory 45 m telescope Galactic Center CO survey have been analyzed to generate a compilation of molecular clouds with intense CO emission in this region.

Highlights of Astronomy, 1992 AbstractThe dynamic subject of the Galactic center is driven mostly by high-resolution imaging both in the continuum and in the spectral line modes in a number of wavelength regimes. An attempt has been made to give a short overview of recent observations in this region, as follows: 1) Unusual characteristics of the population of molecular and dust ...

Luminosity Function of the Perigalactocentric Region [PDF]
, 1996 We present H and K photometry of 42,000 stars in an area of 250 arcmin$^{2}$ centered on the Galactic center. We use the photometry to construct a dereddened K band luminosity function (LF) for this region, excluding the excessively crowded inner 2' of ...

Reconciling 3D Models for the Central 10 pc of the Milky Way
The Astrophysical JournalThe construction of an accurate 3D model of the Milky Way center is necessary to understand inflow processes that drive its overall evolution and to compare our Galactic nucleus to other galaxies’ nuclei.

Key questions about Galactic Center dynamics [PDF]
, 2010 I discuss four key questions about Galactic Center dynamics, their implications for understanding both the environment of the Galactic MBH and galactic nuclei in general, and the progress made in addressing them.

The Observed Galactic Annihilation Line. Possible Signature of the Cluster for Accreting Small Mass Black Holes [PDF]
, 2005 Compton Gamma Ray Observatory, OSSE, SMM, TGRS, balloon and recent INTEGRAL data reveal a feature of the 0.511 MeV annihilation radiation of the Galactic Center with a flux of approximately 5x 10^{-4}~0.511 MeV photons cm^{-2} s^{-1}.

Simulation of the Motion of Stars Escaping from the Galactic Center
Open Astronomy, 2015 Motions of stars escaping from the Galactic center are simulated. It is shown that the Galactic bar reduces the initial velocity needed to escape from the Galaxy.

First Results from SPARO: Evidence for Large-Scale Toroidal Magnetic Fields in the Galactic Center
, 2001 We have observed the linear polarization of 450 micron continuum emission from the Galactic center, using a new polarimetric detector system that is operated on a 2 m telescope at the South Pole.

Candidate selection for the FLAMINGOS-2 galactic center survey [PDF]
, 2008 We present a JHK_s catalog of a 20'×20' region around the Galactic Center observed with the ISPI camera on the 4 m CTIO telescope. The data is being used to select targets for the FLAMINGOS-2 Galactic Center Survey, which will take near-infrared spectra ...
