AMAZE - I. The evolution of the mass–metallicity relation at z $>$ 3
We present initial results of an ESO-VLT large programme (AMAZE) aimed at determining the evolution of the mass-metallicity relation at z > 3 by means of deep near-IR spectroscopy. Gas metallicitiesExpand
A New Picture for the Chemical Evolution of the Galaxy: the Two Infall Model
Resumen en: We present a chemical evolution model for the Galaxy which assumes that the evolution of the halo and thick disk is completely disentangled from the thin...
Abundance Gradients and the Formation of the Milky Way
In this paper we adopt a chemical evolution model, which is an improved version of the Chiappini, Matteucci, & Gratton model, assuming two main accretion episodes for the formation of the Galaxy, theExpand
On the Typical Timescale for the Chemical Enrichment from Type Ia Supernovae in Galaxies
We calculate the Type Ia supernova (SN) rate for different star formation histories in galaxies by adopting the most popular and recent progenitor models. We show that the timescale for the maximumExpand
Dynamical properties of AMAZE and LSD galaxies from gas kinematics and the Tully-Fisher relation at z~3
We present a SINFONI integral-field kinematical study of 33 galaxies at z ∼ 3 from the AMAZE and LSD projects, which are aimed at studying metallicity and dynamics of high-redshift galaxies. TheExpand
Quantifying the uncertainties of chemical evolution studies II. Stellar yields
Context. Galactic chemical evolution models are useful tools for interpreting the large body of high-quality observational data on the chemical composition of stars and gas in galaxies that haveExpand
The evolution of the Milky Way from its earliest phases: Constraints on stellar nucleosynthesis
We computed the evolution of the abundances of O, Mg, Si, Ca, K, Ti, Sc, Ni, Mn, Co, Fe and Zn in the Milky Way. We made use of the most widely adopted nucleosynthesis calculations and compared theExpand
Oxygen, carbon and nitrogen evolution in galaxies
We discuss the evolution of oxygen, carbon and nitrogen in galaxies of different morphological type by adopting detailed chemical evolution models with different star formation histories (continuousExpand
Stellar Mass Loss in Elliptical Galaxies and the Fueling of Active Galactic Nuclei
The connection between some observational properties of active galactic nuclei and their host galaxies is studied using a self-consistent model of galactic evolution which reproduces the mainExpand
Formation and evolution of the Galactic bulge: constraints from stellar abundances
Aims. We compute the chemical evolution of the Galactic bulge in the context of an inside-out model for the formation of the Milky Way. The model contains updated stellar yields from massive stars.Expand
