| Abstract: |
The Local Group (LG) is the closest and thus most accessible place
for seeking detailed information about the assembly and evolutionary
history of dwarf and giant galaxies. However, in order to gain a
broader and more complete view on these processes, we must step
outside its boundaries and investigate different environments. The
CenA/M83 group is a nearby (D∼4 Mpc) dense complex dominated by a
giant elliptical and a giant spiral, hosting more than 60 dwarf
companions with a variety of morphological types and stellar
contents. We study the resolved stellar populations of CenA and
several satellite dwarf galaxies using optical and near-infrared data from space
and ground based telescopes. In this contribution we outline the
results from the analysis of their colour-magnitude diagrams (CMDs). |
