When wave effects of thermal photons become significant, thermal emitters can exhibit intriguing coherent effects. Here, we show that the superradiant emission, which was originally found in quantum emitters, can be realized in resonant thermal emitters. Similar to the superradiance in quantum emitters, the in-phase oscillation of resonant emitters reduces the lifetime of thermal photons in the emitters. Unlike the atomic superradiance, one remarkable consequence of the thermal superradiance is the anomalous power scaling, where the emission power can scale inversely with the number of thermal emitters. More thermal emitters generate less power due to the coherent interference of thermal photons.
