Book excerpt: We also check MSI-based SFHs against those inferred from analysis of the fossil record – from spectral energy distributions (SEDs) of star-forming galaxies in the SDSS, and color magnitude diagrams (CMDs) of resolved stars in dwarf irregular galaxies. Once stellar population age uncertainties are accounted for, the main sequence is in excellent agreement with SED-based SFHs (from VESPA). Extrapolating SFR main sequence observations to dwarf galaxies, we find differences between MSI results and SFHs from CMD analysis of ACS Nearby Galaxy Survey Treasury (ANGST) and Local Group (LG) galaxies. Resolved dwarfs appear to grow much slower than main sequence trends imply, and also slower than slightly higher mass SED-analyzed galaxies. This difference may signal problems with SFH determinations, but it may also signal a shift in star formation trends at the lowest stellar masses.
