SUMMARY:Puzzles in the Structure of Disk Galaxies
DESCRIPTION:Puzzles in the Structure of Disk Galaxies\nProf. Stephane Court
 eau\n\nGalaxies can be described in terms of their structure, dynamics and
  stellar populations.  Some very robust correlations between various 
 galaxy structural properties, such as total luminosity, maximum circular v
 elocity, and size show rather small scatter, hinting at well-regulated gal
 axy formation processes.  A major challenge to understanding thesesca
 ling relations, and ultimately galaxy formation and evolution, is the elus
 ive interplay between visible and dark matter.  I will discuss the la
 test derivations of galaxy scaling relations and their link withmodern cos
 mological models.
