| contents | Quarkonium production is one of the golden probes to study the quark--gluon plasma (QGP). Among many observables, the measurement of azimuthal anisotropies in quarkonium production sheds light on the collective behavior of heavy-flavor particles in a strongly interacting medium. In particular, the measurements of the elliptic flow ($v_{2}$) of quarkonia in Pb--Pb collisions at the LHC provide us direct evidence of heavy quark thermalization in the QGP. In these proceedings, new results of inclusive $\mathrm{J/ψ}$ elliptic flow measurement in Pb--Pb collisions carried out by the ALICE collaboration in Run 3 using three methods including event-plane, scalar-product and multi-particle correlation (cumulant) will be presented. The method of cumulant will give access to the $\mathrm{J/ψ}$ flow fluctuations at forward rapidity. Alongside the new flow measurements of $\mathrm{J/ψ}$, new results of $\mathrmΥ(1S)$ flow measurement at forward rapidity in ALICE Run 3 will be presented as well with comparison to model calculations. |
