The thermal photon emission rate is determined by the spatially transverse, in-medium spectral
function of the electromagnetic current. Accessing the spectral function using Euclidean data
is, however, a challenging problem due to the ill-posed nature of inverting the Laplace trans-
form. In this contribution, we present the first results on implementing the proposal of directly
computing the analytic continuation of the retarded correlator at fixed, vanishing virtuality of the photon via the calculation of the appropriate Euclidean correlator at imaginary spatial momentum. We employ two dynamical O(
