The Chemical Composition of Elliptical Galaxies Through Mid-UV Indices,ide. On the basis of the Index vs [Fe/H] correlations seen in a sample of galactic globular clusters, we derived the chemical composition for all our sample galaxies. All resulting abundances are subsolar with Mg features delivering, on average, the lowest values.

The Rest-Frame UV Spectrum of Elliptical Galaxies at High Redshift,a characteristic structure due to a set of iron and magnesium lines lines at λ?eq 2600–2850 ? in the rest frame. The same feature permits also to estimate the time elapsed since the cessation of star formation. Current efforts at observing high redshift PEGs at the VLT and SUBARU telescopes are brie
