The evolution of the mass-metallicity relation at z~3
R. Maiolino, T. Nagao, A. Grazian +14
We present preliminary 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 spectroscop…
The red and blue galaxy populations in the GOODS field: evidence for an excess of red dwarfs
S. Salimbeni, E. Giallongo, N. Menci +8
We study the evolution of the galaxy population up to z\sim3 as a function of its colour properties. In particular, luminosity functions and luminosity densities have been derived…
A Photometrically Detected Forming Cluster of Galaxies at Redshift 1.6 in the GOODS Field
M. Castellano, S. Salimbeni, D. Trevese +9
We report the discovery of a localized overdensity at z~1.6 in the GOODS-South Field, presumably a poor cluster in the process of formation. The three-dimensional galaxy density ha…
Black hole masses and enrichment of z ~ 6 SDSS quasars
Jaron D. Kurk, Fabian Walter, Xiaohui Fan +7
We present sensitive near-infrared spectroscopic observations for a sample of five z ~ 6 quasars. These are amongst the most distant, currently known quasars in the universe. The s…
Physical properties of z~4 LBGs: differences between galaxies with and without Ly-alpha emission
L. Pentericci, A. Grazian, A. Fontana +5
We have analysed the physical properties of z~4 Lyman Break Galaxies observed in the GOODS-S survey, in order to investigate the possible differences between galaxies where the Ly-…
