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.
