The RHIC-PHENIX experiment has measured the azimuthal anisotropy parameter v{sub 2}, the second harmonic of the azimuthal distribution, for electrons at mid-rapidity (|{eta}| < 0.35) as a function of transverse momentum (0.5 <p{sub T}< 5.0 GeV/c) in Au+Au collisions at {radical}s{sub NN} = 200 GeV. From the result, we have calculated heavy flavor (charm and bottom) electron v{sub 2} by subtracting v{sub 2} of electrons from other sources such as photon conversions and Dalitz decays. At the PHENIX experiment, the nuclear modification factor (R{sub AA}) for the heavy flavor electrons is also measured. The property of the medium-created Au+Au collisions at {radical}s{sub NN} = 200 GeV can be provided to these measurements.
