The transverse momentum dependence of the azimuthal anisotropy parameter v2, the second harmonic of the azimuthal distribution, for electrons at midrapidity (|η|<0.35) has been measured with the PHENIX detector in Au+Au collisions at √sNN=200 GeV. The measurement was made with respect to the reaction plane defined at high rapidities (|η|=3.1-3.9). From the result we have measured the v2 of electrons from heavy flavor decay after subtraction of the v2 of electrons from other sources such as photon conversions and Dalitz decay from light neutral mesons. We observe a nonzero single electron v2 with a 90% confidence level in the intermediate-pT region. The precision of the present data set does not permit us to conclude definitively that heavy quarks exhibit thermalization with the transverse flow of the bulk matter.
