Overview of low p_T photon results from PHENIX at RHIC

Overview of the latest low p _T direct photon measurements by the PHENIX experiment at RHIC is presented. We found a smooth change of the effective temperature as a function of $\sqrt{s_{NN}}$. We studied the scaling properties of the direct photon yield with various global observables. When plotting the direct photon yield as a function of dN _ch/dη a universal scaling independent of the $\sqrt{s_{NN}}$ was observed. (paper)
