RR Lyrae variables in the dwarf spheroidal galaxy Leo I
E. V. Held, G. Clementini, L. Rizzi +3
We report the discovery of a significant population of RR Lyrae variables in the dwarf spheroidal galaxy Leo I. Based on 40 V and 22 B images of the galaxy taken using the ESO Wide…
Wide Field HR diagrams of Local Group Dwarf Galaxies
L. Rizzi, E. V. Held, I. Saviane +3
We present new observations of Sextans and Leo I dwarf galaxies, that provide new insight on their stellar populations. The large sample of stars measured in Sextans allowed us to…
Dwarf galaxies in the Local Group: the VLT perspective
Enrico V. Held
Recent results on the evolution of Local Group dwarf galaxies obtained from VLT imaging and spectroscopy are briefly reviewed, and prospects for dwarf galaxy research at the VLT ar…
Population gradients in nearby dwarf galaxies
Ivo Saviane, Enrico V. Held, Yazan Momany +1
Recent results on the detection of substructure in dwarf spheroidal galaxies are discussed. In most cases they show that, when a galaxy experiences multiple SF episodes, the interm…
