We discuss the PHENIX photon and dilepton data in the context of the Glasma.
We find that the distributions of such electromagnetic production, while
previously not well understood, might now be qualitatively and
semi-quantitatively described after including the essential contribution
arising from a thermalizing Glasma. In particular, the $p_T$ dependence of the
low mass di-lepton excess as measured by PHENIX may be consistent with
production from a transient Bose-Einstein condensate of gluons in the
pre-equilibrium matter.
