Local supermassive black holes, relics of active galactic nuclei and the X-ray background
We quantify the importance of mass accretion during AGN phases in the growth of supermassive black holes (BH) by comparing the mass function of black holes in the local universe with that expectedExpand
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 fundamental relation between mass, SFR and metallicity in local and high redshift galaxies
We show that the mass-metallicity relation observed in the local universe is due to a more general relation between stellar mass M*, gas-phase metallicity and SFR. Local galaxies define a tightExpand
The Supernova rate per unit mass
We compute the rate of supernovae (SNe) of different types along the Hubble sequence normalized to the near- infrared luminosity and to the stellar mass of the parent galaxies. This is made possibleExpand
LSD: Lyman-break galaxies Stellar populations and Dynamics – I. Mass, metallicity and gas at z∼ 3.1
We present the first results of a project, Lyman-break galaxies Stellar populations and Dynamics (LSD), aimed at obtaining spatially resolved, near-infrared (IR) spectroscopy of a complete sample ofExpand
We use hard X-ray data for an "optimal" sample of Seyfert 2 galaxies to derive the distribution of the gaseous absorbing column densities among obscured active nuclei in the local universe. Of allExpand
The Lesser Role of Starbursts in Star Formation at z = 2
Two main modes of star formation are know to control the growth of galaxies: a relatively steady one in disk-like galaxies, defining a tight star formation rate (SFR)-stellar mass sequence, and aExpand
Gas metallicity diagnostics in star-forming galaxies
Generally the gas metallicity in distant galaxies can only be inferred by using a few prominent emission lines. Various theoretical models have been used to predict the relationship between emissionExpand
Massive molecular outflows and evidence for AGN feedback from CO observations
We study the properties of massive, galactic-scale outflows of molecular gas and investigate their impact on galaxy evolution. We present new IRAMPdBI CO(1-0) observations of local ultra-luminousExpand
The relation between AGN hard X-ray emission and mid-infrared continuum from ISO spectra: Scatter and unification aspects ,
We use mid-infrared spectral decomposition to separate the 6  μ m mid-infrared AGN continuum from the host emission in the ISO low resolution spectra of 71 active galaxies and compare the results toExpand
