28 Dec 2018 Li Zongnan Li Zhiyuan Zhou Ping Gao Yu Jiang Xue-Jian Dong Hui

We present a survey of CO(3-2) molecular line emission in the circumnuclear region of M31 with the James Clerk Maxwell Telescope (JCMT), aiming to explore the physical conditions of the molecular gas. Significant CO(3-2) lines are detected primarily along the so-called nuclear spiral, out to a projected galactocentric radius of 700 pc at a linear resolution of ~50 pc... (read more)
