Galaxy Evolution in Dense Environments: Physical and Morphological Properties
Ciria Lima Dias
Galaxy clusters are ideal laboratories for studying galaxy evolution in dense environments, and current multiwavelength surveys allow us to observe changes in the colors and morphology of galaxies across different filters. In this work, we utilize data from the Southern Photometric Local Universe Survey (S-PLUS), which includes 12 filters in the visible range of the spectrum, to analyze galaxies as a whole and to perform bulge-disc decomposition. Studying the distinct components of a cluster galaxy separately is crucial, as these components are influenced by the environment in different ways. We investigate the behavior of structural (Sérsic index and effective radius) and physical (stellar mass and star formation rate) properties of the galaxies and correlate them with the environment (clustercentric distance, local density, and substructure). As a result, we found that the star-forming galaxies in the Hydra cluster have bluer bulges compared to their discs, indicating that the environment is quenching these galaxies from the outside in.
