In today's colloquium I will explain how resolved stellar populations in the nearby Local Group dwarf galaxies have been used to study the detailed chemical, kinematic and star formation history of these nearby small systems. I will focus on the results from the DART (Dwarf Abundances and Radial velocities Team) surveys and also some recent work combining spectroscopy with colour-magnitude diagram analysis to measure the time scale for chemical evolution.
The picture shows an edge-on, warped spiral galaxy, NGC 59007, and an extended stellar tidal stream, created through gravitational interaction.
