Revisiting the Blazar Main Sequence
A. Cavaliere, V. D'Elia
A discussion of the FSRQ -- BL Lac unification. All distinctive features marking these two Blazar subclasses find an unifying explanation if the sources are powered by central engi…
The Connection between BL Lacs and FSRQs
V. D'Elia, A. Cavaliere
We discuss the features that mark the Flat Spectrum Radio Quasars from the BL Lacertae objects. We propose that FSRQs exceeding L = 10^{46} erg/s are powered by black hole accretin…
A Physical Model for Baryons in Clusters of Galaxies
P. Tozzi, A. Cavaliere, N. Menci
The X-ray emission from clusters of galaxies is one of the best observational probe to investigate the distribution of dark matter at intermediate and high redshifts. Since the dis…
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…
Small groups of Galaxies as Cosmological Clocks
P. Tozzi, F. Governato, A. Cavaliere
We study the formation and evolution of small groups of galaxies using new Monte Carlo simulations. These are directly based on the random walk approach to the statistics of conden…
