C_2H, HC_3N and HNC observations in OMC-2/3
《Research in Astronomy and Astrophysics》2011年第6期671-678,共8页Qiang Liu Ji Yang Yan Sun Ye Xu 
supported by the National Natural Science Foundation of China (Grant Nos. 11003046, 11073054, 10733030 and 10621303);the National Basic Research Program of China (973 Program, Grant 2007CB815403)
For the first time, the OMC-2/3 region was mapped in C2H （1–0）, HC3N （10–9） and HNC （1–0） lines. In general, the emissions from all the three molecular species reveal an extended filamentary structure. The di...

Multiwavelength study of low-luminosity 6.7-GHz methanol masers
《Research in Astronomy and Astrophysics》2011年第2期137-155,共19页Yuan-Wei Wu,Ye Xu and Ji Yang Purple Mountain Observatory,Chinese Academy of Sciences,Nanjing 210008,China 
supported by National Natural Science Foundation of China (Grant Nos.11073054,10733030,10703010 and 10621303);the National Basic Research Program of China (2007CB815403);supported in part by the Key Laboratory for Radio Astronomy,CAS
We present results of 13CO（1-0）,C18O（1-0）,and HCO＋（1-0） map observations and N2H＋（1-0） single point observations directed towards a sample of nine low-luminosity 6.7-GHz masers.N2H ＋ line emission has been ...
