2014 Science Highlights |
The Jet and Arc Molecular Clouds toward Westerlund 2 |
Furukawa et al. (2014) present new
12CO and 13CO (J=2-1 and J=1-0) observations of two
molecular clouds made with NANTEN2 and the Mopra Telescope. The so-called
"jet" and "arc" clouds are loacted toward the stellar cluster Westerlund 2,
RCW49, and the TeV gamma-ray source HESS J1023-575. Furukawa et al. suggest
that neither are physically linked with Westerlund 2 but are located at a
greater distance around 7.5 kpc. |
