Discovery of molecular shells associated with supernova remnants. (II) Kesteven 75
Yang Su, Yang Chen, Ji Yang +4
The young composite supernova remnant (SNR) Kesteven 75, with a pulsar wind nebula at its center, has an unusual morphology with a bright southern half-shell structure in multiwave…
Discovery of Molecular Shells Associated with Supernova Remnants. I. Kesteven 69
Xin Zhou, Yang Chen, Yang Su +1
Supernova remnant (SNR) Kes 69 is morphologically characterized by brightened radio, infrared, and X-ray emission on the southeastern rim, with the 1720 MHz OH masers detected in t…
Molecular Gas and Star formation in ARP 302
Yiping Ao, Dinh-V-Trung, Jeremy Lim +2
We present the Submillimeter Array observation of the CO J=2-1 transition towards the northern galaxy, ARP 302N, of the early merging system, ARP 302. Our high angular resolution o…
A 12CO, 13CO, and C18O Survey of Infrared Dark Clouds
Fujun Du, Ji Yang
InfraRed Dark Clouds (IRDCs) are extinction features against the Galactic infrared background, mainly in mid-infrared band. Recently they were proposed to be potential sites of mas…
Disks around massive young stellar objects: are they common?
Zhibo Jiang, Motohide Tamura, Melvin G. Hoare +4
We present K-band polarimetric images of several massive young stellar objects at resolutions 0.1-0.5 arcsec. The polarization vectors around these sources are nearly centro…
High Resolution Imaging of Molecular Outflows in Massive Young Stars
Keping Qiu, Qizhou Zhang, Henrik Beuther +1
We present high angular resolution observations toward two massive star forming regions IRAS 18264-1152 and IRAS 23151+5912 with the Plateau de Bure Interferometer (PdBI) in the Si…
