Studying the components of galaxies is crucial for understanding their evolution. The BUDDI-MaNGA project aims to explore the evolution and morphological transformations of galaxies through the star-formation histories of their bulges and discs. This project provides the largest sample of clean bulge and disc spectra extracted from IFU datacubes, which will contribute to answering questions about galaxy formation and evolution.
Many galaxies display clear bulges and discs, and understanding how these components form is a vital step towards understanding how the galaxy has evolved into what we see today. The BUDDI-MaNGA project aims to study galaxy evolution and morphological transformations through the star-formation histories of the bulges and discs. We have applied our buddi software to galaxies from the MaNGA Survey in the SDSS DR15 in order to isolate their bulge and disc spectra, from which we derived their stellar populations. To date, this work provides the largest sample of clean bulge and disc spectra extracted from IFU datacubes using the galaxies light profile information, and will form the basis for a series of papers aiming to answer open questions on how galaxies have formed and evolved, and the role of their individual structures. This paper presents an introduction to the project, including an overview of these fits, a characterization of the sample, and a series of tests on the fits to ensure reliability.
