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.
