GRB091127/SN2009nz and the VLT/X-shooter spectroscopy of its host galaxy: probing the faint end of the mass-metallicity relation
S. D. Vergani, H. Flores, S. Covino +36
We perform a detailed study of the gamma-ray burst GRB091127/SN2009nz host galaxy at z=0.490 using the VLT/X-shooter spectrograph in slit and integral-field unit (IFU). From the an…
Advances on GRB as cosmological tools
G. Ghirlanda
Several interesting correlations among Gamma Ray Bursts (GRB) prompt and afterglow properties have been found in the recent years. Some of these correlations have been proposed als…
"Ab initio" models of galaxy formation: successes and open problems
Gabriella De Lucia
In the past decades, different approaches have been developed in order to link the physical properties of galaxies to the dark matter haloes in which they reside. In this review, I…
Early metal enrichment in high-redshift quasars
R. Maiolino
Quasars are powerful systems whose spectrum is rich of metal features that allow us to investigate the chemical evolution of galaxies at very high redshift, even close to the reion…
Uncertainties and Systematic Effects on the estimate of stellar masses in high z galaxies
S. Salimbeni, A. Fontana, E. Giallongo +4
We discuss the uncertainties and the systematic effects that exist in the estimates of the stellar masses of high redshift galaxies, using broad band photometry, and how they affec…
The formation and evolution of early-type galaxies : solid results and open questions
Andrea Cimatti
The most recent results and some of the open key questions on the evolution of early-type galaxies are reviewed in the general cosmological context of massive galaxy formation.
