Near-IR Polarimetry Around 30 Doradus: I. Separation of the Galactic Sources
Kim Jaeyeong, Pak Soojong, Choi Minho +7
A 20 arcmin \times 20 arcmin region around 30 Doradus in the Large Magellanic Cloud (LMC) is observed and analyzed in the near-infrared. We obtain polarimetry data in the J, H, and…
Submillimeter Observations of Dense Clumps in the Infrared Dark Cloud G049.40-00.01
Miju Kang, Minho Choi, John H. Bieging +3
We obtained 350 and 850 micron continuum maps of the infrared dark cloud G049.40-00.01. Twenty-one dense clumps were identified within G049.40-00.01 based on the 350 micron continu…
Radio Imaging of the NGC 1333 IRAS 4B Region
Minho Choi, Jeong-Eun Lee
The NGC 1333 IRAS 4B region was observed in the 6.9 mm and 1.3 cm continuum with an angular resolution of about 0.4 arcseconds. IRAS 4BI was detected in both bands, and BII was det…
Radio Imaging of the NGC 1333 IRAS 4A Region: Envelope, Disks, and Outflows of a Protostellar Binary System
Minho Choi, Miju Kang, Ken'ichi Tatematsu +2
The NGC 1333 IRAS 4A protobinary was observed in the 1.3 cm and 6.9 mm continuum and the ammonia and SiO lines, with an angular resolution of about 0.4 arcseconds. The continuum ma…
Rotation of the NGC 1333 IRAS 4A2 Protostellar Jet
Minho Choi, Miju Kang, Ken'ichi Tatematsu
The bipolar jet of the NGC 1333 IRAS 4A2 protostar shows a velocity gradient in the direction perpendicular to the jet axis. This lateral velocity gradient can be seen throughout t…
