dc.description.abstract We use the HI velocity profiles of The HI Nearby Galaxy Survey (THINGS) galaxies to study the phase structure of the interstellar medium (ISM) and its relation to galaxy properties and morphology. To construct high signal-to-noise (S/N) profiles, we use a method analogous to the stacking method sometimes used in high redshift HI observations. We call these high S/N profiles 'super profiles'. By decomposing the super profiles into Gaussian components, we find broad and narrow components in all our analyzed galaxies. en_ZA
