SNe at z~1 • High redshift (z>0.5) • Ia: cosmology • CC: tracer of SFH SNe: • metal production • feedback for galaxy formation • thermal history of ICM and IGM Mannucci et al. 2007
SNe associated to GRB Della Valle et al. (2006a) Della Valle et al. (2006b) • Long GRB: death of a massive star • diversity of SNe • z>1 • Imaging and Spectroscopy • LGS: DL, sky coverage
Black Hole in Galactic Nuclei • correlation BH mass – bulge mass • Coformation and coevolution galaxy-central BH • Feedback Measuring the BH mass: • Star dynamics • Gas dynamics • (size of BLR, line width, reverbaration mapping) Only ~40 measures Sphere of influence: BH gravitational field = Galactic Radius = 0.1” for M = 108M⊙ σ = 200 Km/sec D = 20 Mpc Marconi & Hunt (2003)
