Isolated Dwarf Galaxies of the Local Group: Searching for UV-background Iimprint in the Star Formation History
Sebastian Luis Hidalgo (IAC)

We present the detailed star formation histories (SFHs) of a sample of isolated dwarf galaxies of the Local Group . The SFHs were derived from deep color-magnitud diagrams obtained from observations with the ACS camera on board HST. The SFHs reach the oldest ages of the stars with accuracy enough to search for the imprint of the UV-background in the early stages of these galaxies.
