The Hierarchical Assembly of Elliptical Galaxies

• Galaxy Formation movies
• Making a spiral galaxy -- quiescent evolution (Steinmetz et al)
• Making an elliptical galaxy -- active merging (Steinmetz et al)
• Hierarchical assembly of cluster galaxies -- violent density field (Rudick, Mihos, & McBride 2008)
  

• A sample merger tree for an elliptical galaxy
  
• Clues from low to moderate redshift
• Star formation or galaxy assembly? "Old" galaxies at high redshift
• Figures from Cimatti et al 2004:
  
• Spectra of high-z "old" galaxies
• Morphologies of high-z "old" galaxies
• Ellipticals at low redshift
