The General Assembly of Galaxy Halos:

Structure, Origin and Evolution

--------------------

Scientific Program

--------------------

Topics covered by the IAU Symp. 317

• Do all galaxies have stellar halos? What are the structure parameters for radial density profiles, the angular momentum distribution and dynamical equilibrium?
• Stellar tracers of the MW halo and nearby galaxies; the stellar population of star clusters and their contribution to the galaxy halos
• Substructure and smooth components in galaxy halos
• First stars and stochastic enrichment in the early Galaxy
• How do age and metallicity vary as function of radius and kinematics? As function of morphological types, i.e. disks vs. ellipticals?
• Galactic archaeology with (ongoing and future) large astrometric, spectroscopic & photometric surveys
• The connection among Dwarf galaxy / Ultra Compact Dwarf / Ultra Faint Dwarfs / Globular Cluster and their connection to the assembly of halos
• Do we see halos forming at high z? How do they grow their mass over time?
• How do the halos form and what is the connection with galaxy fomation ?
• How similar the MW halo is to other halos in the Local Group and beyond?
