摘要：

We simulate direct photon production in the evolution of viscous quark-gluon plasma medium. Photons from Compton and annihilation processes are considered. The viscous effect on photon production is very strong and reliable simulation is possible only in a limited p(T) range. For minimally viscous fluid (eta/s = 0.08), direct photons can be reliably computed only up to p(T) <= 1.3 GeV. With reduced viscosity (eta/s = 0.04), the limit increases to p(T) <= 2 GeV.
