Abstract:The study of the luminosity contribution from TP-AGB stars to the stellar populations of galaxies is crucial to determine their physical parameters (e.g., stellar mass and age). We use a sample of 84 nearby disk galaxies to explore diverse stellar population synthesis models with different luminosity contributions from TP-AGB stars. We fit the models to optical and NIR photometry, on a pixel by pixel basis. The statistics of the fits show a preference for a low luminosity contribution (i.e., high mass-to-light… Show more
