SELF-GRAVITY AND ANGULAR MOMENTUM TRANSPORT IN EXTENDED GALACTIC DISKS
Abstract
We demonstrate a significant difference in the angular momentum transport properties of galactic disks between regions in which the interstellar medium is single phase or two phase. Our study is motivated by observations of H i in extended galactic disks which indicate velocity dispersions of nonthermal origin, suggesting that turbulence in the gas may be contributing significantly to the observed dispersion. To address this, we have …
