PHENIX results on direct photon production from Au+Au collisions

<!--HTML-->PHENIX measurements of low $p_T$ direct photons in Au+Au collisions at 200 GeV show large yields that have simultaneously a large anisotropies with respect to the reaction plane, and that scale with the charged multiplicity to a power of 5/4, independent of  transverse momentum and...

description <!--HTML-->PHENIX measurements of low $p_T$ direct photons in Au+Au collisions at 200 GeV show large yields that have simultaneously a large anisotropies with respect to the reaction plane, and that scale with the charged multiplicity to a power of 5/4, independent of  transverse momentum and collision centrality. Calculations of thermal photon emission fall short in describing these three features. Furthermore, a recent publication of the STAR collaboration indicates lower direct photon yields in Au+Au collisions than observed by PHENIX.  In order to provide new PHENIX has shown first results from Au+Au data taken in 2014. These data have 10 fold statistics compared to published results. In this talk we will show the latest direct photon results from this data set.
