A constant N $_{2}$ H $^{+}$ (1-0)-to-HCN(1-0) ratio on kiloparsec scales

M. J. JimÃ©nez-Donaire, A. Usero, I. BeÅ¡liÄ +24

Nitrogen hydrides such as NH $_{3}$ and N $_{2}$ H $^{+}$ are widely used by Galactic observers to trace the cold dense regions of the interstellar medium. In external galaxies, because of l…

New Constraints on the $^{12}$ CO(2-1)/(1-0) Line Ratio Across Nearby Disc Galaxies

J. S. den Brok, D. Chatzigiannakis, F. Bigiel +18

Both the CO(2-1) and CO(1-0) lines are used to trace the mass of molecular gas in galaxies. Translating the molecular gas mass estimates between studies using different lines requi…
