    "abstract": "A general relationship is presented between the statistics of thermal\nradiation from a random medium and its scattering matrix S. Familiar results\nfor black-body radiation are recovered in the limit S to 0. The mean photocount\nis proportional to the trace of 1-SS^dagger, in accordance with Kirchhoff\u0027s law\nrelating emissivity and absorptivity. Higher moments of the photocount\ndistribution are related to traces of powers of 1-SS^dagger, a generalization\nof Kirchhoff\u0027s law. The theory can be applied to a random amplifying medium (or\n\"random laser\") below the laser threshold, by evaluating the Bose-Einstein\nfunction at a negative temperature. Anomalously large fluctuations are\npredicted in the photocount upon approaching the laser threshold, as a\nconsequence of overlapping cavity modes with a broad distribution of spectral\nwidths.",
