The colours of the Sun
Johan Holmberg, Chris Flynn, Laura Portinari
We compile a sample of Sun-like stars with accurate effective temperatures, metallicities and colours (from the UV to the near-IR). A crucial improvement is that the effective temp…
The Initial Mass Function in disc galaxies and in galaxy clusters: the chemo-photometric picture
L. Portinari
The observed brightness of the Tully-Fisher relation suggests a low stellar M/L ratio and a "bottom-light" IMF in disc galaxies, but the corresponding efficiency of chemical enrich…
Simulating galaxy clusters -- I. Thermal and chemical properties of the intra-cluster medium
A. D. Romeo, J. Sommer-Larsen, L. Portinari +1
We have performed a series of N-body/hydrodynamical (TreeSPH) simulations of clusters and groups of galaxies, selected from cosmological N-body simulations within a CDM framewor…
The Formation of Fossil Galaxy Groups in the hierarchical Universe
E. D'Onghia, J. Sommer-Larsen, A. D. Romeo +4
We use a set of twelve high-resolution N-body/hydrodynamical simulations in the CDM cosmology to investigate the origin and formation rate of fossil groups (FGs), which are X-ra…
