Star Formation Histories (SFHs) reveal physical processes that influence howgalaxies form their stellar mass. We compare the SFHs of a sample of 36 nearby(D $\leq$ 4 Mpc) dwarf galaxies from the ACS Nearby Galaxy Survey Treasury(ANGST), inferred from the Color Magnitude Diagrams (CMDs) of individuallyresolved stars in these galaxies, with those reconstructed by broad-bandSpectral Energy Distribution (SED) fitting using the Dense Basis SED fittingcode. When comparing individual SFHs, we introduce metrics for evaluating SFHreconstruction techniques. For both the SED and CMD methods, the mediannormalized SFH of galaxies in the sample shows a period of quiescence atlookback times of 3-6 Gyr followed by rejuvenated star formation over the past3 Gyr that remains active until the present day. To determine if theserepresent special epochs of star formation in the D $\leq$ 4 Mpc portion of theLocal Volume, we break this ANGST dwarf galaxy sample into subsets based onspecific star formation rate and spatial location. Modulo offsets between themethods of about 1 Gyr, all subsets show significant decreases and increases intheir median normalized SFHs at the same epochs, and the majority of theindividual galaxy SFHs are consistent with these trends. These results motivatefurther study of potential synchronized star formation quiescence andrejuvenation in the Local Volume as well as development of a hybrid method ofSFH reconstruction that combines CMDs and SEDs, which have complementarysystematics.
