An evolutionary model for GHz Peaked Spectrum Sources. Predictions for high frequency surveys
G. De Zotti, G. L. Granato, L. Silva +2
We have explored, in the general framework of the ``young source'' scenario, evolutionary models for GHz Peaked Spectrum (GPS) galaxies and quasars which reproduce the observed cou…
Joint Formation of QSOs and Spheroids: QSOs as clocks of star formation in Spheroids
G. L. Granato, L. Silva, P. Monaco +4
Direct and indirect observational evidence leads to the conclusion that high redshift QSOs did shine in the core of early type proto-galaxies during their main episode of star form…
Joint formation of bright quasars and elliptical galaxies in the young Universe
P. Monaco, P. Salucci, L. Danese
We show that the mass function of black holes expected from the past quasar activity (both visible and obscured) is consistent with the number of dormant black holes found in the b…
Polarization fluctuations due to extragalactic sources
G. De Zotti, C. Gruppioni, P. Ciliegi +2
We have derived the relationship between polarization and intensity fluctuations due to point sources. In the case of a Poisson distribution of a population with uniform evolution…
Joint Cosmological Formation of QSOs and Bulge-dominated Galaxies
Pierluigi Monaco, Paolo Salucci, Luigi Danese
Older and more recent pieces of observational evidence suggest a strong connection between QSOs and galaxies; in particular, the recently discovered correlation between black hole…
New photometric models of galactic evolution applied to the HDF
G. L. Granato, L. Silva, L. Danese +4
We summarize our modelling of galaxy photometric evolution (GRASIL code). By including the effects of dust grains and PAHs molecules in a two phases clumpy medium, where clumps are…
