Non-equilibrium excitation of methanol in Galactic molecular clouds: multi-transitional observations at 2 mm

V. I. Slysh, S. V. Kalenskii, I. E. Val'tts +2

We observed 14 methanol transitions near lambda=2 mm in Galactic star-forming regions. Broad, quasi-thermal J(0)-J(-1)E methanol lines near 157 GHz were detected toward 73 sources.…
