Query: Lattice QCD estimate of the quark-gluon plasma photon emission rate   We present a computation of the photon emission rate of the quark-gluon
plasma from two-flavor lattice QCD at a temperature of 254 MeV, which follows
up on the work presented in [1]. We perform a continuum extrapolation of the
vector-current correlator, and consider a linear combination of the Lorentz
indices corresponding to a UV-finite spectral function. To extract the spectral
function from the lattice correlators, an ill-posed inverse problem, we model
the spectral function with a Pad\'e ansatz. We further constrain our analysis
by simultaneously fitting data with different momenta. We present results for a
multi-momentum fit including the three smallest momenta available from our
lattice analysis.
