Spiral shocks and the formation of molecular clouds in a two phase medium

Abstract

We extend recent numerical results (Dobbs et al. 2006) on molecular cloud formation in spiral galaxies by including a multi-phase medium. The addition of a hot phase of gas enhances the structure in the cold gas, and significantly increases the fraction of molecular hydrogen that is formed when the cold gas passes through a spiral shock. The difference in… (More)
