Scope, redefined

• What were the reasons why we did so well?
• What are the open (and important) questions?
• How can we fit in, still be competitive but still
  have fun?

Basic picture

• Where do stars form?
• Split SFR (IRUV) into red/blue
• Most SF in blue disks (Wolf05 Bell05)
• Where do stars go?
• IF stars formed in blue galaxies stayed there,
  predict dramatic growth of blue stellar mass
  function, and little growth of red mass function
  (solid lines)
• Instead, mass in red galaxies grows (Bell 04
  Borch06 Brown 06 Faber 07)
• Transfer of mass from blue ? red galaxies
  suspect mergers as driver
• Despite intense activity, galaxies still follow
  their scaling relations (Barden05 McIntosh05
  Kassin06)

Open questions2

• Are galaxies quenching as centrals or as
  satellites?
• Mergers vs. environment AGN feedback Group
  catalogues
• What regulates black hole growth and its effect
  on the galaxy?
• What physics regulates gas supply to non-quenched
  galaxies?
• SFRs as proxies, gas census

• galaxy formation has e-folded
• we need to focus even more on the things that
  really matter to us.
• Assets
• beautiful theory wing
• Powerful AGN group
• VST/VISTA, LUCIFER, ESO (Large programmes only),
  PanSTARRS, WFC3, JWST
• Questions
• how hard do we push for zgt1? lead a major
  GEMS-class effort (WFC3/LUCIFER/VISTA)?
• are we overstretched as it is?
