Description

The evidence for correlations between particles significantly separated in pseudorapidity in both small and large colliding systems represents one of the most remarkable findings observed at the LHC and at RHIC. Long-range correlations in heavy-ion collisions are considered signatures for the creation of a strongly-coupled quark-gluon plasma, which converts the initial anisotropy of the fireball into final state hadron momentum correlations. In proton-proton and proton-nucleus collisions, where the formation of a QGP was initially not expected, their nature is not yet fully understood. Measurements involving heavy quarks, due to their early formation time and large mass, can provide unique constraints on the origin of these phenomena.
In this presentation, a selection of the latest heavy-flavour measurements performed by ALICE to constrain the collective properties of pp, p--Pb and Pb--Pb collisions will be presented. This will include the final results of the elliptic-flow coefficient of heavy-flavour decay muons at forward rapidity in high-multiplicity p--Pb collisions at $\sqrt{s_{\rm NN}}$ = 8.16 TeV, as well as elliptic-flow coefficient measurements of non-prompt D$^{0}$ mesons in Pb--Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV.
