Quarkonium measurements in nucleus-nucleus collisions with ALICE

Heavy quarks are produced in the early stages of nucleus-nucleus collisions and can therefore provide important insight into Quark-Gluon Plasma (QGP). Quarkonia proposed as crucial probes to study QGP. The extent medium modification for heavy-quark quarkonium production heavy-ion is measured terms a nuclear factor $R_{\rm AA}$, defined yield divided by relative cross section pp scaled overlap function. A possible path-length dependent dissociation, well contribution (re-)generation quarkonia from heavy medium, would lead an azimuthal anisotropy reaction plane. In this contribution, recent ALICE measurements Pb-Pb at $\sqrt{s_{\rm NN}}$ = 5.02 TeV will be discussed both mid- forward rapidity. dependence AA}$ on centrality $p_{\rm T}$ J/$\psi$, $\Upsilon$(1S), $\Upsilon$(2S), J/$\psi$ elliptic flow $v_{2}$ shown. experimental data current theoretical model calculations also discussed.
