SUMMARY:How simple are galaxies?
DESCRIPTION:How simple are galaxies?\nDr. Yago Ascasibar\n\nGalaxies are ar
 guably complex systems. However, they also display many scaling relations 
 between their physical properties, hinting that it might be possible to su
 mmarize all this complexity within a few phenomenological parameters. In t
 his talk, we will first address the question of how many parameters are in
 deed necessary in order to describe a galaxy, and then discuss some of the
 m in detail, aiming towards a self-consistent, cartoon (yet remarkably acc
 urate) picture of galaxy formation and evolution.
