1. Tuesday Summary Clusters - Galaxy assembly history through cosmological simulations can form bimodal cluster distributions. - Universal shape of the joint mass/age distribution of clusters ~ M -2  -1 - caused by similar disruption histories. - Dissection of stellar distribution in 47 Tuc indicates old age, and possible internal  variations (continuous?). - SF continuous, traces gas. Infant mortality through gas expulsion after cluster forms. IMF normal. - Evaporation rate of GCs (driven by internal relaxation) is a modest power of density. MF is not universal.

6. Tuesday Summary Galaxies - Predictions from hierarchical galaxy formation tested through stellar pops: (e.g., [  /Fe] in halo > dSphs). - Sgr leading/trailing arms indicates MW halo triaxial (vertically-oriented). 5-8 associated clusters, mostly in trailing arm. - Substructure is prominent among nearby galaxies. - M31 inner disturbance all produced by single stream, extended GCs bridge galaxies/clusters on r h vs L plane. - Lots of M31 outer substructure, large scale metal-poor streams…kinematic probes well underway. - NGC 147 and 185 dominated by intermediate ages (3-10 Gyrs), intermediate [Fe/H] (-1.0 - -2.0), and rotation.
