Abstract
Understanding the luminosity of unresolved stellar populations is recognized as a crucial aspect of galaxy evolution studies. This presentation will address how detailed information from resolved stellar populations is leveraged to infer the physical properties of unresolved populations through stellar population synthesis (SPS) models. A key focus will be placed on the role of the initial mass function (IMF) and the impact of dust in shaping the observed luminosity. By bridging theoretical frameworks with observational data, models can be refined to enhance the interpretation of the luminosity of distant, unresolved populations. Recent advancements in SPS modeling will be presented, demonstrating how the incorporation of IMF and dust properties facilitates the extraction of meaningful insights regarding the composition and evolution of galaxies. This approach is posited as a powerful framework for understanding the interplay between stars and their environment in both nearby and high-redshift galaxies.
