$α$ -enhanced Astrochemistry: the Carbon cycle in extreme galactic conditions

Thomas G. Bisbas, Zhi-Yu Zhang, Eda Gjergo +8

Astrochemistry has been widely developed as a power tool to probe physical properties of the interstellar medium (ISM) in various conditions of the Milky Way (MW) Galaxy, and in ne…

An improved method to measure $^{12} C /^{13} C$ and $^{14} N /^{15} N$ abundance ratios: revisiting CN isotopologues in the Galactic outer disk

Yichen Sun, Zhi-Yu Zhang, Junzhi Wang +7

The variations of elemental abundance and their ratios along the Galactocentric radius result from the chemical evolution of the Milky Way disks. The $^{12} C /^{13} C$ ratio in p…
