Galaxy Formation and Evolution
•Theory: Different origins for bulges, disks, and pseudobulges -hierarchical merging, accretion, monolithic collapse and secular evolution (e.g. Cole et al 2000, Kormendy and Kennicutt 2004)
• CDM: Mass- Luminosity, Spin-size-surface brightness -Dalcanton et al (1997), Mo et al (1998), Navarro and Steinmetz (2000), Bouwens and Silk (2004)
•High z surveys (e.g. GOODS, GEMS)
•Provide a representative, complete sample at low redshift
•Need to measure SB distribution but with something more quantitative than Hubble classes -Bulge-Disk decomposition
•Definitive Local calibration
The Millennium Galaxy Catalogue (MGC)
•144 pointings at δ=0 (10h00m-14h50min)•37 sq degrees along an equatorial strip•High Galactic Latitude
