Gas infall towards Sgr A* from the clumpy circumnuclear disk
María Montero-Castaño, Robeson M. Herrnstein, Paul T. P. Ho
We present the first large-scale mosaic performed with the Submillimeter Array (SMA) in the Galactic center. We have produced a 25-pointing mosaic, covering a ~2' x 2' area around…
Three-Dimensional Observations of H_2 Emission around Sgr A East - I. Structure in the Central 10 Parsecs of Our Galaxy
Sungho Lee, Soojong Pak, Minho Choi +6
We have obtained velocity-resolved spectra of the H_2 v=1-0 S(1) (lambda = 2.1218 micron) emission line at 2 arcsec angular resolution (or 0.08 pc spatial resolution) in four regio…
Hot Molecular Gas in the Nuclear Region of IC 342
Maria Montero-Castano, Robeson M. Herrnstein, Paul T. P. Ho
We present the first interferometric detection of extragalactic NH_3(6,6) emission in the nearby galaxy IC 342 made using the VLA. The data have a resolution of 7.8''x 5.0'' and tr…
Exploring High-Velocity NH_3(6,6) Emission at the Center of our Galaxy
Jennifer L. Donovan, Robeson M. Herrnstein, Paul T. P. Ho
Using the NH\3 (6,6) transition, which samples dense () molecular gas with an energy above ground of 412 K, we find hot gas at high velocities (--142 to --210 km s$^{-…
The Nature of the Molecular Environment within 5 pc of the Galactic Center
R. M. Herrnstein, P. T. P. Ho
We present a detailed study of molecular gas in the central 10pc of the Galaxy through spectral line observations of four rotation inversion transitions of NH3 made with the VLA. U…
Detection of the Intrinsic Size of Sagittarius A* through Closure Amplitude Imaging (includes Online Supporting Material)
Geoffrey C. Bower, Heino Falcke, Robeson M. Herrnstein +3
We have detected the intrinsic size of Sagittarius A*, the Galactic Center radio source associated with a supermassive black hole, showing that the short-wavelength radio emission…
