    The star formation and chemical evolution history of the Fornax dwarf spheroidal galaxy
    We present deep photometry in the B, V and I filters from CTIO/MOSAIC for about 270 000 stars in the Fornax dwarf spheroidal galaxy, out to a radius of rell ≈ 0...

    The star formation timescale of elliptical galaxies. Fitting [Mg/Fe] and total metallicity simultaneously
    The alpha element to iron peak element ratio, for example [Mg/Fe], is a commonly applied indicator of the galaxy star formation timescale (SFT) since the two...
