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…
Millimeter-band Surveys of Extragalactic Sources
Gianfranco De Zotti, Francesca Perrotta, Gian Luigi Granato +5
Surveys at mm wavelengths emphasize rare classes of extragalactic radio sources characterized by spectra keeping flat or inverted up to high frequencies (such as blazars, GPS sourc…
Spheroidal Galaxies/QSOs Connection
Luigi Danese, Gian Luigi Granato, Laura Silva +2
In view of the extensive evidence of a tight inter-relationship between spheroidal galaxies (and galactic bulges) and massive black holes hosted at their centers, a consistent mode…
QSOs and Spheroidal Galaxies
G. L. Granato, G. DeZotti, L. Silva +2
In view of the extensive evidence of tight inter-relationships between spheroidal galaxies (and galactic bulges) with massive black holes hosted at their centers, a consistent mode…
Clustering properties and gravitational lensing of forming spheroidal galaxies
F. Perrotta, M. Magliocchetti, C. Baccigalupi +5
We show that the predictions of the recent physical model by Granato et al. (2001) are fully consistent with the available estimates of the clustering properties of galaxies at (su…
