Measurement of electro-magnetic radiation at RHIC-PHENIX Original Research Article

Recent results on direct photons and dileptons from the PHENIX experiment opened up a possibility of landscaping electro-magnetic radiation over various kinetic energies in heavy ion collisions. Results on direct photon measurement in Au+Au collisions at View the MathML source are discussed from the point of view of structure function and isospin effect. It is supported by the first measurement of direct photons at View the MathML source in the same collisional system.
