| Abstract: |
The details of the early star formation history of isolated dwarf galaxies can shed light on the role of the cosmic re-ionization and supernova feedback in galaxy formation and evolution. In this paper, we present the project Local Cosmology from Isolated Dwarfs (LCID), aimed at deriving detailed star formation histories for a sample of Local Group isolated dwarf galaxies. To accomplish this goal we have collected, using the ACS on board the HST, color– magnitude diagrams reaching their oldest main sequence turnoff (V ≃ 29 mag) with good photometric accuracy. Some results are briefly discussed. |
