. I present 2-D angular power spectra of cold H I emission and optical dust reflection tracing the H I in the Pleiades reflection nebula. This analysis reveals a uniform power-law slope of -2.8 over 5 orders of magnitude in scale, from tens of parsecs down to tens of astronomical units. NASA ADS Abstract .

The quantity of dust in a spiral disk can be estimated using the dust's typical emission or the extinction of a known source. In this paper we compare two techniques, one based on emission and one on absorption, applied to sections of 14 disk galaxies. ... Hence, they depend differently on the average number and optical depth of ISM structures in the disk. The small-scale geometry of the cold ISM is critical for accurate models of the overall energy budget of spiral disks. ...
