This project presents a novel approach to study galaxy evolution by investigating the stellar population properties within different structural components of galaxies, utilizing data from the J-PLUS and SDSS-IV MaNGA IFU survey. Moving beyond the conventional focus on radial gradients and the simplistic bulge-plus-disk dichotomy, it aims to conduct a comprehensive comparison of integrated…
Stellar population synthesis models are invaluable to modern Extragalactic Astrophysics. They provide means to extract stellar masses, star formation histories, chemical enrichment histories and dust content of galaxies from their integrated spectral energy distributions, colours or spectra. These models have been evolving through decades. On the one hand, this happens as a natural conseq…
Stellar population (SP) models are invaluable to modern Extragalactic Astrophysics. They provide means to extract stellar masses, dust content, star formation and chemical enrichment histories of galaxies from their integrated spectral energy distributions, colours or spectra. We have pioneered the publication of high resolution spectral models with variable abundance patterns in Coelho e…

The Brazilian astronomical community is currently involved in photometric surveys that together will observe more than 15,000 square degrees of the sky. The set of filters from two of these surveys, J-PLUS and S-PLUS, is composed of 5 broadband filters based on SDSS filters, complemented by 7 narrowband filters covering the major stellar indices of 3700 to 9000. These surveys will produce…
Galactic bulges are structures present in the central part of various types of galaxies, in general characterized by spheroidal morphology which are gravitationally supported by velocity dispersion of the constituent stars. Although visually simple structures, detailed studies of the kinematic properties in bulges show that they may be quite different from one another -- they may be suppo…
The chemical composition of stars in a galaxy encloses valuable information about the past history of star formation and chemical enrichment. This depends on the complex interplay between infall of pristine gas and its consumption by star formation, heavy element production, and the potential ejection of metal-enriched gas from the galaxy, for example by supernova explosions and active ga…

Chemical abundances are used in galactic archeology techniques to infer the formation and evolution of the components in our Galaxy, stellar populations and galaxies in general. So far, chemical archeology studies have largely required the use of spectral data. Yet, the novel photometric survey J-PAS, with its system of 54 narrow-band filters, will effectively provide low resolution spect…
