1)Missing satellite problem
2) Star formation problem
3) Galaxy core/cusp problem
4) Thin disk galaxy problem
1) Dwarf galaxy cosmology
2) Globular cluster cosmology
Comparison of mass functions for the MW dSphs and Via Lactea II simulation
Mv-log re(pc) for dwarf galaxies, globular clusters, and UCDs.
Most of the new dwarfs (filled circles) are from SDSS.

Distribution of MW satellites

Tolstoy etal (2009)
Very metal poor!
Harris (2009) CFHT/Megaprime:
1d x 1d for M87
*HST/ACS images: They are genuine GCs!
-Williams et al (2007) 4 IGCs in Area 4
-Lee, Lim, et al (2010, in prep) several new IGCs
Are they really GCs? How about compact dwarfs (UCDs, DTGCs)?
Faber-Jackson relations from GCs to galaxy clusters.
(Tellerud et al 2010)
With the GMT observations (GMACS, NIRMOS, Gclef, GMTNIRS, GMTIFS, etc) of dwarf galaxies and globular clusters,
1) study dark matter in galaxies and clusters
2) study the early star formation history
3) find the first objects in the universe
