DESCRIPTION:Speakers: Ciria Lima Dias (Departamento de Astronomía\, Unive
 rsidad de La Serena\, Chile)\n\n\n\nGalaxy clusters are key environments f
 or studying how galaxies evolve and how environmental processes affect the
 ir morphology and star-formation activity. In this seminar\, I will presen
 t our analysis of the nearby Antlia cluster\, tracing galaxy properties fr
 om its central region out to 5R200. Using the 12-band photometry of S-PLUS
 \, we combine structural information from multi-band GALFITM modelling wit
 h Hα-based estimates of star formation to investigate galaxy morphology\,
  star-formation activity\, local environment\, and substructure. We identi
 fy multiple substructures extending to the cluster outskirts\, with outer 
 groups dominated by star-forming and late-type galaxies\, while the massiv
 e central substructure hosts a more environmentally processed population. 
 The persistence of star-forming and late-type systems even within the viri
 alised region further points to ongoing galaxy accretion and transformatio
 n. Together\, these results reveal Antlia as a dynamically active cluster 
 still assembling its galaxy population. I will also discuss the connection
  of this work with 4MOST/CHANCES\, for which S-PLUS provides the photometr
 ic target catalogue in the Antlia region.\n \n\nJoin Zoom Meeting  \n \
