Title:
Dark matter and black holes over cosmic time
Date: Monday, December 11th, 2006
Time: 12:00 noon
Venue: Villa Bazzoni

Abstract:
Dark matter and black holes are essential ingredients to
understand the formation and evolution of early-type galaxies. Dark
halos dominate their gravitational potential, while accretion onto the
central supermassive black hole may provide energy feedback to
regulate star formation. Tight empirical scaling relations such as the
Fundamental Plane and the MBH-sigma relation suggest an interplay
between dark matter, stars and black holes. I will present some
observational results on the evolution of dark matter, stars and black
holes over cosmic time and their implication in terms of early-type
galaxies formation.
