    "abstract": "We study the radiation of thermal photons and dileptons likely to be produced\nin relativistic heavy ion collisions. We find that the thermal photon\nmultiplicity scales with the charged pion multiplicity as $dN_{ch}/dy)^\\alpha$\nwith $\\alpha\\sim 1.2$ for a transversely expanding system, contrary to the\ngeneral belief of a quadratic dependence. The scaling is shown to be valid,\nboth for real and virtual photons. The coefficient of proportionality at a\ngiven energy may help us identify the appropriate equation of state of hot\nhadronic matter produced in such collisions.",
