We present new deep color-magnitude diagrams at different galactocentric distances of the Local Group dwarf spheroidal galaxy Fornax, and preliminary results on...

A comparison is carried out among the star formation histories of early-type galaxies in fossil groups, clusters and low density environments. Although they...

Local Group (LG), the nearest and most complete galactic environment, provides valuable information on the formation and evolution of the Universe. Studying...

We present V, I CCD photometry of the Sextans dwarf spheroidal galaxy (dSph) in the Local Group. Images of the galaxy were taken by Suprime-Cam on Subaru...

We present a new method to solve the star formation history (SFH) of a complex stellar population system from the analysis of the color-magnitude diagram (CMD)...

We present a quantitative analysis of the star formation history (SFH) of 12 fields in the Small Magellanic Cloud (SMC) based on unprecedented deep [(B-R),R]...

We present a progress report of a project to study the quantitative star formation history (SFH) in different parts of the Small Magellanic Cloud (SMC). We use...

The SFH of galaxies can be studied with detail in nearby systems which are resolvable into individual stars. In such case, the color-magnitude (CM) diagram can...
