    "abstract": "A general theory is presented for the spatial correlations in the intensity\nof the radiation emitted by a random medium in thermal equilibrium. We find\nthat a non-zero correlation persists over distances large compared to the\ntransverse coherence length of the thermal radiation. This long-range\ncorrelation vanishes in the limit of an ideal black body. We analyze two types\nof systems (a disordered waveguide and an optical cavity with chaotic\nscattering) where it should be observable.",
