Population gradients and photometric metallicities in early- and transition-type dwarf galaxies: Clues from the Sculptor group
S. Lianou, E. Grebel, G. S. Da Costa +3
We focus on the resolved stellar populations of one early- and four transition-type dwarf galaxies in the Sculptor group, with the aim to examine the potential presence of populati…

The star formation history of the Sculptor Dwarf Irregular Galaxy
Sophia Lianou, Andrew A. Cole
[abridged] We study the resolved stellar populations and derive the SFH of the SDIG, a gas-rich dwarf galaxy member of the NGC7793 subgroup in the Sculptor group. We construct a CM…

Spectroscopic versus Photometric Metallicities: Milky Way Dwarf Spheroidal Companions as a Test Case
Sophia Lianou, Eva K. Grebel, Andreas Koch
Aims. The method of deriving photometric metallicities using red giant branch stars is applied to resolved stellar populations under the common assumption that they mainly consist…
