What can the Dwarf and Compact Stellar System Population of the Fornax Galaxy Cluster tell us about its Formation History?

Yasna Ordenes , PUC Chile, ARI
Given its proximity, the Fornax cluster is a goldmine for studying the formation and evolution of galaxies and compact stellar systems (CSSs), globular clusters (GCs), and ultra compact dwarf galaxies (UCDs) in a cluster environment. We have obtained deep multi-passband imaging as part of the Next Generation Fornax Survey in optical (u′g′i′) bands with DECam and near-infrared (JKs) bands with VIRCam. I will present the latest results of my PhD thesis work. First, I will start with the dwarf galaxy population in the outer Fornax cluster region where we have discovered 271 dwarf galaxies. Second, I will show the results for the nuclei in Fornax dwarf galaxies where we have detected a bimodal nuclei mass distribution and the nucleus mass vs. galaxy mass relation becomes shallower for less massive galaxies. Finally, I will show the current status of the CSSs research in the central region, the spatial distribution in terms of age, metallicity and mass distribution.
