Description
Electromagnetic probes are considered as clean messengers from the hot dense medium created in the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC). In this talk, I will review the theoretical developments in the study of electromagnetic radiation in relativistic heavy-ion collisions. The recent progress in the rates for photon and lepton pair production is discussed. Together with the improvements in the hydrodynamic descriptions of the bulk medium, I will emphasize the combined efforts to resolve the ``direct photon flow puzzle'' in the RHIC experiments. Further prediction of the direct photon production in small collision systems at the top RHIC and BES relevant energies can elucidate the properties of quark gluon plasma.
