On the Dust Extinction in High-z Galaxies and the Case of Extremely Red Objects
Andrea Cimatti, Simone Bianchi, Andrea Ferrara +1
We present the preliminary results of Monte Carlo simulations aimed to investigate the effects of realistic dust extinction (absorption + scattering) on the colours of high-z galax…
Probing ISM Models with H-alpha observations
Andrea Ferrara
I review the capabilities of H observations to constrain some aspects of the current models of the interstellar medium. In particular, it is shown that turbulence is a necessary…
Dust in Hot Environments: Giant Dusty Galactic Halos
Andrea Ferrara
I review some of the evidences for dust in the Local Bubble and in galactic halos and show that a general mechanism based on radiation pressure is capable of evacuating dust grains…
Hydrodynamics of Cloud Collisions in 2D: The Fate of Clouds in a Multi-phase Medium
Francesco Miniati, T. W. Jones, Andrea Ferrara +1
We have studied head-on collisions between equal-mass, mildly supersonic (Mach number 1.5) HI clouds, in a standard Two-phase ISM (T_cl = 74 K, n_cl = 22 cm^-3, χ= 100). We explore…
Ly-alpha Clouds Associated with Pop III Objects in Cold Dark Matter Models
Benedetta Ciardi, Andrea Ferrara
We present a semi-analytical model to test the hypothesis that Ly-alpha QSO absorption lines originate in gaseous halos produced by multiple supernova explosions occurring in Pop I…
Energy Dissipation in Interstellar Cloud Collisions
Massimo Ricotti, Andrea Ferrara, Francesco Miniati
We present a study of the kinetic energy dissipation in interstellar cloud collisions. The main aim is to understand the dependence of the elasticity (defined as the ratio of the f…
