Semi-Analytic Models on the Molecular andNeutral Gas in Galaxies

摘要

We introduced a semi-analytic model to study the detail of radial related processes on galaxy disks. Based on this recipe, we can calculate neutral and molecular gas in interstellar medium, and include the molecular phase into star formation recipes. From our model, we repro-duced the radial surface density profiles and mass functions shown in the observational results. We can also give some predictions and explanations to the scale relations of neutral and molecular gas in disk galaxies.
