Description
Photons and dileptons offer themselves as 'clean' probes of the quark-gluon plasma because they are unlikely to reinteract once produced. Their emission rates are given via the vector spectral function $\rho_{\mu\nu}$, an object that can ultimately be reconstructed by analytic continuation of lattice data. To help scrutinise ensuing systematic uncertainties, we determine the NLO corrections to $\rho_{\mu\nu}$ in all domains that affect the associated imaginary-time correlator, namely for energies above, below and in the vicinity of the light cone.
