  • Claudia Lagos: The atomic and molecular gas content of galaxies
  • Abstract: The latest observations of the carbon monoxide and atomic hydrogen contents of local and high-redshift galaxies, coupled with how these correlate with star formation activity, have revolutionized our ideas about how to model star formation and the interstellar medium in a galactic context. A successful theory of galaxy formation has to explain some key facts: (i) high-redshift galaxies have higher molecular gas fractions and star formation rates than local galaxies, (ii) scaling relations between the molecular, atomic and stellar mass of local galaxies show a close to linear relation between the molecular and stellar mass and almost no correlation between atomic and stellar mass, and (iii) the global abundance of atomic hydrogen evolves very weakly with time. I will describe the approach of semi-analytic models and the efforts done with them to put together these pieces in an ab-initio galaxy formation model. I will also show that the multi-phase ISM treatment needed to put together this puzzle, allows us to improve our understanding of the effect of SNe induced outflows on galaxy properties and star formation quenching. I will present observable predictions and what still needs to be done in these models to allow robust testing by the new observations expected from e.g. ASKAP, SKA, ALMA, PdBI.
