ALICE results on quarkonia

The ALICE experiment has measured quarkonia production in pp and Pb-Pb collisions at the CERN LHC, in the rapidity ranges image and image. Quarkonia are considered to be a sensitive probe of deconfinement, and a detailed differential study of their yields can give important information on the properties of the medium created in heavy-ion collisions. In this paper, we will mainly discuss the centrality dependence of the image nuclear modification factors, as well as their image and y dependence in bins of centrality, which will be then compared to theoretical models. Preliminary results on the image elliptic flow and on image production will also be shown.
