    "abstract": "We study C70 fullerene matter waves in a Talbot-Lau interferometer as a\nfunction of their temperature. While the ideal fringe visibility is observed at\nmoderate molecular temperatures, we find a gradual degradation of the\ninterference contrast if the molecules are heated before entering the\ninterferometer. A method is developed to assess the distribution of the\nmicro-canonical temperatures of the molecules in free flight. This way the\nheating-dependent reduction of interference contrast can be compared with the\npredictions of quantum theory. We find that the observed loss of coherence\nagrees quantitatively with the expected decoherence rate due to the thermal\nradiation emitted by the hot molecules.",
