SUMMARY:Puzzles in the Structure of Disk Galaxies\, Astronomy Colloqui
 um\, Stephane Courteau\, Queen's University
DESCRIPTION:Galaxies can be described in terms of their structure\, dy
 namics<br><br>
\nand stellar populations.  Some very robust correlatio
 ns between<br><br>
\nvarious galaxy structural properties\, such as to
 tal luminosity\,<br><br>
\nmaximum circular velocity\, and size show r
 ather small scatter\,<br><br>
\nhinting at well-regulated galaxy forma
 tion processes.  A major<br><br>
\nchallenge to understanding these sc
 aling relations\, and ultimately<br><br>
\ngalaxy formation and evolut
 ion\, is the elusive interplay between<br><br>
\nvisible and dark matt
 er.  I will discuss the latest derivations<br><br>
\nof galaxy scaling
  relations and their link with modern<br><br>
\ncosmological models.
