  The PHENIX experiment discovered a large excess of low-$p_{T}$ direct photons
in Au+Au collisions at 200 GeV compared to reference p+p collisions, which has
been attributed to thermal radiation from the medium produced in the
collisions. At the same time the excess photons show a large azimuthal
anisotropy, expressed as Fourier coefficients $v_{2}$ and $v_{3}$. These
surprising results have not yet been fully described by theoretical models. We
will present the results obtained from real photons in the electromagnetic
calorimeter and photons converted on the outer shell of the Hadron Blind
Detector. PHENIX has also developed a new technique to identify conversion
photons without assuming the radius where the conversion happened. This method
greatly increases the available statistics and reduces systematic
uncertainties.
