Photons from nuclear collisions at RHIC energies

We model the hot and dense strongly interacting matter produced in high-energy heavy-ion collisions using relativistic hydrodynamics. Several different sources of real photons produced during these collisions are considered and their relative importance is assessed. We include contributions from QCD jets, which are allowed to lose and gain energy as they proceed through the hot matter. This is treated within the AMY formalism. We obtain photon spectra, RγAA, and vγ2 in agreement with measurements performed by the PHENIX Collaboration.
