Description
Anisotropic flow is a key observable to characterize the system created in heavy-ion collisions, as it is sensitive to its initial state, transport properties, the equation of state and freeze-out conditions. In this presentation, we present the anisotropic flow coefficients of inclusive charged particles in Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 and 5.02 TeV, and Xe-Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV. The results are reported for a wide range of particle transverse momenta within the pseudo-rapidity range $|\eta| < 0.8$ at different collision centralities. The energy and system dependence are found to place strong constraints on the temperature dependence of $\eta/s$ and the modeling of the initial state respectively. We also present detailed studies of flow fluctuations in heavy-ion collisions, in order to precisely characterize the underlying flow probability distribution function. We find evidence of non-Bessel-Gaussian fluctuations and we discuss the origin of this observation.
