The ACS LCID Project XI. On the early time resolution of LG dwarf galaxy SFHs: Comparing the effects of reionization in models with observations

Understand

The analysis of the early star formation history (SFH) of nearby galaxies, obtained from their resolved stellar populations is relevant as a test for cosmological models.

• However, the early time resolution of observationally derived SFHs is limited by several factors.
• Thus, direct comparison of observationally derived SFHs with those derived from theoretical models of galaxy formation is potentially biased.
• Here we investigate and quantify this effect.
