Quarkonia and heavy-flavour results from ALICE

Quarkonia and heavy flavour are important probes of the hot and dense QCD medium formed in high-energy heavy-ion collisions, through the modification of their yields and kinematical distributions. Measurements of their production in proton-nucleus collisions are crucial for the interpretation of heavy-ion results, as they allow one to study cold nuclear matter effects. Quarkonia and heavy-flavour production in Pb-Pb collisions at the LHC is measured in ALICE at both forward and mid-rapidity, by exploiting several experimental techniques. The main results obtained in Pb-Pb and p-Pb collisions are presented
