Images IV: Strong evolution of the oxygen abundance in gaseous phases of intermediate mass galaxies since z=0.8

M. Rodrigues, F. Hammer, H. Flores +22

Intermediate mass galaxies (logM(Msun)>10) at z~0.6 are the likeliest progenitors of the present-day numerous population of spirals. There is growing evidence that they have evolve…

On the absorption of X-ray bright broad absorption line quasars

Margherita Giustini, Massimo Cappi, Cristian Vignali

Most X-ray studies of BALQSOs found significant (N_H~10^{22-24} cm^{-2}) intrinsic column densities of gas absorbing an underlying typical power-law continuum emission, in agreemen…

Open clusters as key tracers of Galactic chemical evolution. III. Element abundances in Berkeley 20, Berkeley 29, Collinder 261, and Melotte 66

P. Sestito, A. Bragaglia, S. Randich +3

Galactic open clusters are since long recognized as one of the best tools for investigating the radial distribution of iron and other metals. We employed FLAMES at VLT to collect U…

Hydrodynamical simulations of Galactic fountains I: evolution of single fountains

C. Melioli, F. Brighenti, A. D'Ercole +1

The ejection of the gas out of the disk in late-type galaxies is related to star formation and is due mainly to Type II supernovae. In this paper we studied in detail the developme…

Disentangling the Galaxy at low Galactic latitudes

M. Cignoni, M. Tosi, A. Bragaglia +2

We have used the field stars from the open cluster survey BOCCE, to study three low-latitude fields imaged with the Canada-France-Hawaii telescope (CFHT), with the aim of better un…

Searching for Cool Core Clusters at High redshift

Joana S. Santos, Piero Rosati, Paolo Tozzi +3

We investigate the detection of Cool Cores (CCs) in the distant galaxy cluster population, with the purpose of measuring the CC fraction out to redshift 0.7 < z < 1.4. Using a samp…
