1. ‘3D’ Data Sets are ABSOLUTELY Crucial to Answer the Important Questions of Galaxy Formation and Evolution
Galaxy dynamical masses, gas masses
Spatially resolved distributions of SF, gas, stellar populations, metallicities
Rotation curves & connection to halo; angular momentum distribution
Co-evolution of massive black holes and host galaxies
Roles of mergers vs secular evolution
Bulge vs disk formation
Roles of stellar and AGN feedback

3. 3D Observations of AGN and High-z Galaxies: Some Questions for Discussion
1) Rephrasing Eric’s question: We’re now doing “low-z” science at high redshift! What are the most important lessons to be learned from nearby galaxies?
- extracting/modeling dynamics
- best line tracers for star formation, dynamics
- best local Universe templates
- synergies between optical/IR and (sub)mm 3D observations (unfortunately no HI at high-z!)
- …

4. 3D Observations of AGN and High-z Galaxies: Some Questions for Discussion
2) Are high-z disks really disks? Are high-z mergers really mergers? Is it all outflows? How do we distinguish amongst them? What about minor mergers?
3) How do we establish the M- relation at high-z? How well calibrated is it at low-z? Do black holes form first? What does this mean for “co-evolution of black holes and host galaxies”?

5. 3D Observations of AGN and High-z Galaxies: Some Questions for Discussion
4) What is the relative importance of cold accretion vs mergers in galaxy formation? How do we get an observational handle on “cold accretion” at high-z ?
5) What improvements/considerations should be made to simulations (of mergers, cold accretion, etc.) based on the data?
6) Lots of other questions?
