Simulating galaxy clusters : the ICM and the galaxy populations
Alessio D. Romeo, J. Sommer-Larsen, L. Portinari
Cosmological LambdaCDM TreeSPH simulations of the formation and evolution of galaxy groups and clusters have been performed. The simulations include: star formation, chemical evolu…

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…
