Reproducing the CO-to-H₂ conversion factor in cosmological simulations of Milky-Way-mass galaxies [PDF]

, 2020
We present models of CO(1–0) emission from Milky-Way-mass galaxies at redshift zero in the FIRE-2 cosmological zoom-in simulations. We calculate the molecular abundances by post-processing the simulations with an equilibrium chemistry solver while ...
