Müller, Oliver; Rejkuba, Marina; Pawlowski, Marcel S.; Ibata, Rodrigo A; Lelli, Federico; Hilker, M; Jerjen, Helmut


Dwarf galaxy satellite systems are essential probes to test models of structure formation, making it necessary to establish a census of dwarf galaxies outside of our own Local Group. We present deep FORS2 VI band images from the ESO Very Large Telescope (VLT) for 15 dwarf galaxy candidates in the Centaurus group of galaxies. We confirm nine dwarfs to be members of Cen A by measuring their distances using a Bayesian approach to determine the tip of the red giant branch luminosity. We have also...[Show more]
