Galaxy metallicity near and far
F. Mannucci, G. Cresci
Metallicity appears to be one the most important tool to study formation and evolution of galaxies. Recently, we have shown that metallicity of local galaxies is tightly related no…
Gas accretion as the origin of chemical abundance gradients in distant galaxies
G. Cresci, F. Mannucci, R. Maiolino +3
It has recently been suggested that galaxies in the early Universe can grow through the accretion of cold gas, and that this may have been the main driver of star formation and ste…
The bright end of the z ~ 7 UV Luminosity Function from a wide and deep HAWK-I survey
M. Castellano, A. Fontana, D. Paris +23
(Abridged) We present here the second half of an ESO Large Programme, which exploits the unique combination of area and sensitivity provided in the near-IR by the camera Hawk-I at…
A decline and fall in the future of Italian Astronomy?
Angelo Antonelli, Vincenzo Antonuccio-Delogu, Andrea Baruffolo +89
On May 27th 2010, the Italian astronomical community learned with concern that the National Institute for Astrophysics (INAF) was going to be suppressed, and that its employees wer…
A fundamental relation between mass, SFR and metallicity in local and high redshift galaxies
F. Mannucci, G. Cresci, R. Maiolino +2
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 d…
Dynamical properties of AMAZE and LSD galaxies from gas kinematics and the Tully-Fisher relation at z~3
A. Gnerucci, A. Marconi, G. Cresci +10
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 ga…
