- Draw a sketch of the galaxy edge-on
- what's the rotation curve if there were only the supremassive BH, if it
were constant density, the one actually measured?
- what does this imply? about the density of DM? do you know of any physical
process which would lead to this r-dependence of density
- where are the globular clusters? how many are there?
- Draw a sketch of the Milky Way? Label distances. What are the stellar populations and scale heights (4 of them not including globular clusters)?
- What is the density of halo stars?
- What is the density of stars in the solar neighborhood? (AB)
