    "abstract": "We calculate the spectra of high energy photons emitted in relativistic Au+Au\ncollisions for various centralities and compare to data recently collected at\nthe Relativistic Heavy Ion Collider by the PHENIX collaboration. Our results\nfor photons from primary hard scatterings and photons from interactions of jets\nwith the medium are consistent with the measurements of neutral pion and direct\nphoton production in p+p collisions and give a good description of direct\nphoton spectra measured in Au+Au collisions. The contribution of photons from\njet-to-photon conversion in the medium can be as large as the photon yield from\nhard scatterings in the momentum range p_T = 2...6 GeV/c. We show that this\nnovel mechanism is not ruled out by any existing data.",
