The deuterium fractionation of NH in massive star-forming regions
Yuqiang Li, Junzhi Wang, Juan Li +6
Deuteration is sensitive to environmental conditions in star-forming regions. To investigate NHD chemistry, we compared the spatial distribution of ortho-NHD $1_{11}^s-1_{0…

A Yebes W band Line Survey towards an Unshocked Molecular Cloud of Supernova Remnant 3C391: Evidence of Cosmic-Ray-Induced Chemistry
Tian-Yu Tu, Prathap Rayalacheruvu, Liton Majumdar +3
Cosmic rays (CRs) have strong influences on the chemistry of dense molecular clouds (MCs). To study the detailed chemistry induced by CRs, we conducted a Yebes W band line survey t…

Large-Scale Mapping Observations of DCN and DCO toward Orion KL
Kotomi Taniguchi, Prathap Rayalacheruvu, Teppei Yonetsu +14
We present emission maps (1.5'1.5' scale, corresponding to 0.18 pc) of the DCN () and DCO () lines in the 2 mm band toward the Orion KL region obtained wi…
