Tomography of the Ophiuchus Molecular Cloud with Velocity Features in C${}_2$H $N=1-0$ spectra: A Pilot Study of Coherent Sub-structures

Lei qian, Zhichen Pan, Dongyue Jiang +1

The C${}_2$H $N=1-0$ transition was used to investigate the possible line of sight sub-structures from the dense and optically thick in ${}^{13}$CO $J=1-0$ regions in the Ophiuchus sta…
