The role of the Initial Mass Function in modelling the Intra-Cluster Medium
L. Portinari
The expected metal enrichment of the intra-cluster medium (ICM) and the partition of metals between cluster galaxies and the hot ICM depends on the stellar Initial Mass Function (I…
Mass-to-Light ratio, Initial Mass Function and chemical evolution in disc galaxies
L. Portinari, J. Sommer-Larsen, R. Tantalo
Cosmological simulations of disc galaxy formation, when compared to the observed Tully-Fisher relation, suggest a low Mass-to-Light (M/L) ratio for the stellar component in spirals…
Coupling Chemical Evolution with SPH
G. Carraro, L. Portinari, C. Lia
We present a new statistical algorithm of Chemical Evolution implemented into the Tree-SPH code developed by Lia & Carraro (2000 MNRAS 314, 145).
A chemical evolution model for galaxy clusters
L. Portinari, A. Moretti, C. Chiosi
We develop a toy-model for the chemical evolution of the intracluster medium, polluted by the galactic winds from elliptical galaxies. The model follows the "galaxy formation histo…
Chemical Evolution of Clusters of Galaxies
L. Portinari, A. Moretti, C. Chiosi
The high metallicity of the intra-cluster medium (ICM) is generally interpreted on the base of the galactic wind scenario for elliptical galaxies. In this framework, we develop a t…
On radial gas flows, the Galactic Bar and chemical evolution in the Galactic Disc
L. Portinari, C. Chiosi
We develop a numerical chemical model allowing for radial flows of gas, with the aim to analyse the possible role of gas flows in the chemical evolution of the Galactic Disc. The d…
