Description: The PHENIX experiment at RHIC has measured electron-positron pairs from various collision systems. Comparing dilepton data from AuAu to pp collisions revealed two striking features: (i) a large excess of the dilepton yield at low mass and low pt in central AuAu and (ii) a significant enhancement of direct real photon radiation. Both features can be interpreted as radiation from the hot quark matter produced at RHIC. Unlike at lower beam energies, at RHIC the contribution from the hot hadronic phase alone seems insufficient to account for the data. This would suggests large a contribution from a partonic phase. Data analysis, experimental results and comparison to theoretical models will be presented.
