A common trend in the chemical evolution of Local Group dwarf spheroidals and Damped Ly-alpha systems
G. Vladilo, L. Sbordone, P. Bonifacio
We compare chemical abundances of Local Group dwarf spheroidals, obtained from recent UVES/VLT observations, and of high redshift Damped Lyman alpha systems (DLAs), corrected for d…

Clues to the origin of metals in the Ly-alpha forest
S. Lopez, S. D'odorico, S. L. Ellison +1
We analyze the z=2 Ly-alpha and CIV forest along two adjacent lines-of-sight at high S/N and spectral resolution to assess the question of the origin of metals in the intergalactic…

Variable stars as tracers of stellar populations in Local Group galaxies: Leo I and NGC 6822
L. Baldacci, F. Matonti, L. Rizzi +5
Results are presented of a study of the variable star populations in the dwarf spheroidal galaxy Leo I and in the dwarf irregular galaxy NGC 6822, based on time series photometry o…
