The formation and evolution of Active Galactic Nuclei (AGN),
attributed to accreting massive black holes (BHs), are closely related to
the formation and evolution of the galaxies which host them.
Our group has been studying the co-evolution of AGN, BHs, and their
host galaxies for several years now.
We rely on a multiwavelength approach, from the millimeter and the
IR to the X-ray. Specifically, our group is engaged in studies of:
-
The structure and properties
of the circumnuclear medium of AGN and radio galaxies, with
application to AGN unification
(Sperello di Serego Alighieri,
Guido Risaliti,
Marco Salvati,
Guidetta Torricelli)
-
Spectral energy distributions of AGN, with particular regard
to bolometric corrections, the extreme IR spectral region,
and the AGN contribution to the cosmic background
(Emanuele Nardini,
Guido Risaliti,
Marco Salvati,
Eleonora Sani)
-
Masses of BHs and correlations with their host galaxies
in the context of formation and co-evolution scenarios
(Leslie Hunt,
Guido Risaliti,
Eleonora Sani)
-
Diagnostics of AGN and starburst components in Ultraluminous
and Luminous Infrared Galaxies (ULIRGs and LIRGs) through hard
X-ray and infrared spectroscopy of dust features
(Emanuele Nardini,
Guido Risaliti,
Marco Salvati,
Eleonora Sani)
-
AGN fueling mechanisms and relation to star formation through
morphology and dynamics of molecular gas in the circumnuclear
regions of AGN
(Viviana Casasola,
Leslie Hunt)
