Title:
Mass, Metallicity and Dynamics of high-redshift galaxies
Date: Wednesday, June 11th, 2008
Time: 12:00
Venue: Villa Bazzoni

Abstract:
We present the first results of two ongoing projects aimed at studying the
detail properties of galaxies at z>3:
LSD (Lyman-break galaxies Stellar populations and Dynamics)
and AMAZE (Assessing the Mass Abundance redshift Evolution).
These projects use deep near-infrared
IFU spectroscopic observations of a sample of ~40 LBGs at z>3
to estimate gas-phase metallicity and dynamical properties.
These galaxies already follow a well-defined mass-metallicity
relation which shows a strong evolution to z=2 and z=0.
This result puts severe constraints on the
models of galaxy evolution involving stellar winds, AGN feedback and
galaxy merging.
