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…
Ammonia Imaging of the Disks in the NGC 1333 IRAS 4A Protobinary System
Minho Choi, Ken'ichi Tatematsu, Geumsook Park +1
The NGC 1333 IRAS 4A protobinary was observed in the ammonia (2, 2) and (3, 3) lines and in the 1.3 cm continuum with a high resolution (about 1.0 arcsec). The ammonia maps show tw…
Observations of B335 in the Millimeter Continuum and the 226 GHz H2CO Line
Minho Choi
The protostar B335 was observed in the 1.3 mm continuum and in the H2CO 312 - 211 line with an angular resolution of about 8 arcsec. The mass of the inner envelope detected by the…
Observations of Water Masers in the NGC 1333 IRAS 4 Region
Geumsook Park, Minho Choi
The NGC 1333 IRAS 4 region was observed in the 22 GHz H2O maser line with an angular resolution of about 0.08 arcseconds. Two groups of masers were detected, one near IRAS 4A and t…
