Description
RHIC data taken over two decades showed that even charm quarks thermalize in the hot system formed in Au+Au collisions at $\sqrt{s_{NN}}=$ 200 GeV. These measurements were constrained to the mid-rapidity region, where charm production peaks. The question is what is the longitudinal extension of the charm thermalization and how that would impact the quantification of charm diffusion in the quark-gluon plasma. It also raises the question on how the charm flow can affect bound state charmonium production by charm recombination. The PHENIX collaboration measured muons from open heavy flavor and $J/\psi$ decays at rapidity range 1.2$<|y|<$2.2 in Au+Au collisions at $\sqrt{s_{NN}}=$ 200 GeV. Their second Fourier component $v_2$ of azimuthal distribution relative to the reaction plane of the collision were measured for the first time at these large rapidities at RHIC. This presentation will summarizes these results and discuss them along with different theoretical scenarios.
