Recent theory developments in electromagnetic radiation from relativistic heavy-ion collisions are reviewed. Electromagnetic observables can serve as a thermometer, a viscometer, and tomographic probes to the collision system. The current status of the "direct photon flow puzzle" is highlighted.

Thermal Spectra Without Detailed Balance
Thermal spectra can be produced by certain classes of emission kernels without probe thermalization, as when the differential cross section depends on angle but not on the Mandelstam variable s, providing a kernel-bas...
