A Physical Model for the joint evolution of high-z QSOs and Spheroids
Gian Luigi Granato, Laura Silva, Luigi Danese +2
We summarize our physical model for the early co-evolution of spheroidal galaxies and of active nuclei at their centers. Our predictions are in excellent agreement with a number of…

Nearby early-type galaxies with ionized gas. Characterization of the underlying stellar population
F. Annibali, R. Rampazzo, A. Bressan +4
We present a preliminary analysis of the sample of early type galaxies of Rampazzo et al. (2005), selected to build a data-set of spectral properties of well studied early-type gal…

Observational tests of the evolution of spheroidal galaxies and predictions for SIRTF/Spitzer cosmological surveys
Laura Silva, Gianfranco De Zotti, Gian Luigi Granato +2
Granato et al(2004) have elaborated a physically grounded model exploiting the mutual feedback between star-forming spheroidal galaxies and the active nuclei growing in their cores…
