Beschreibung:
<jats:p> We investigate automatic γ-ray photon quenching in compact non-thermal sources. This is an auto-regulating network of processes that consists of photon-photon absorption and synchrotron emission of the produced e<jats:sup>-</jats:sup> e<jats:sup>+</jats:sup> pairs and operates non linearly whenever the γ-ray luminosity exceeds a critical value. We present expressions for this quantity and discuss our results. </jats:p>
