Local Dwarf Galaxy Archaeology
Abstract
Local dwarf galaxies retain a record of high-redshift and metal-poor stellar populations. Resolved stellar spectroscopy provides insights into the first stars and galaxies, the smallest dark matter halos, and the first stellar explosions. ELTs with multi-object R=5k-30k spectroscopy will enable such studies for galaxies throughout the Local Group.
