The Impact of Energy Feedback on Quasar Evolution and Black Hole Demographics
V. Vittorini, F. Shankar, A. Cavaliere
We investigate how accretion episodes onto massive black holes power quasars and AGN while they accumulate mass into the holes. We compute both the trend and the stochastic compone…
Early Hierarchical Formation of Massive Galaxies Triggered By Interactions
N. Menci, A. Cavaliere, A. Fontana +3
To address the problem concerning the early formation of stars in massive galaxies, we present the results of a semi-analytic model of galaxy formation which includes a physical de…
The Rise and Fall of the Quasars
A. Cavaliere, V. Vittorini
The coherent rise and fall of the quasar population is discussed in terms of gas accretion onto massive black holes, governed by the hierarchically growing environment. The rise is…
The Twofold Quasar-galaxy Connection
A. Cavaliere, V. Vittorini
The rise and the fall of the QS population are explained in terms of massive black holes forming/accreting during the assemblage of the host galaxies, and of accretion rekindled by…
