• Direct photons
• quark gluon plasma
• thermal photons
• energy loss

The recently published PHENIX data of direct photons at low p, from Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC) energy root s(NN)=200 GeV have attracted much theoretical interest. Here I review our theoretical calculation which successfully reproduces the measured p(t) spectra of direct photons from Au+Au at different centralities over a wide p(t) range, in order to show a close relation between hadronic observables and those of direct photons.
