Abstract
ALICE (A Large Hadron Collider Experiment) at the CERN LHC is aimed at studying the hot and dense QCD matter which is formed in high-energy heavy-ion collisions. A selection of the results obtained by ALICE in lead-lead collisions will be presented; this will include collective phenomena, particle spectra and correlations, heavy flavors and jets. Results from the recent p-Pb run will be also discussed.

A preliminary measurement of the direct photons spectrum in 0-40% most central Pb-Pb collisions for 0.5-2.5 GeV/c transverse momentum yields a temperature of 304 ± 51 MeV, which is about 40% larger than the one found at RHIC
Additional information has been obtained by studying the nuclear suppression factor of heavy flavour decay electrons at mid–rapidity and of muons at forward rapidity: as shown in Fig. 8, a significant suppression of charm and beauty is observed in central Pb–Pb collisions
