... VOLUME**, **YEAR OF PUBLICATION** **NAMES OF EDITORS** Multiscale Structure in Dust Reflection and Cold H i Steven J. Gibson National Astronomy and Ionosphere Center Abstract. I present 2-D angular optical dust reflection tracing the H analysis reveals a uniform p ower-law in scale, from tens of parsecs down to p ower sp ectra of cold H i emission and i in the Pleiades reflection nebula. ... However, H i and dust should be well mixed in cold gas, so dust may trace H i structure at fine scales. ...

... The Thickness of Stellar Disks in Early-type Galaxies E. M. Chudakova* and O. K. Sil'chenko ** Sternberg Astronomical Institute, Lomonosov Moscow State University, Moscow, Russia Received August 19, 2013; in final form, October 30, 2013 Abstract--We suggest and justify a new photometric method enabling the derivation of the relative thickness of a galactic disk from the two-dimensional surface-brightness distribution of the galaxy in the plane of the sky. ... The galaxies are non-interacting. ...
