在轻子发射模型中，blazar的宽带SED有两个较宽的光谱分量，分别是相对论电子的同步辐射和SSC辐射。在高态阶段，高频SSC分量往往主导低频同步辐射分量，这意味着电子的逆康普顿SSC损耗至少等于或大于电子的同步辐射损耗。线性同步辐射冷却通常包含在blazar的辐射模型中，然后必须由SSC冷却来补充。在这里，我们给出了单能注入的同步加速器和非线性同步加速器自康普顿冷却联合作用下相对论电子运动方程的解析解。我们计算了单能电子通过同步加速器和SSC冷却所产生的随时间变化的通量和积分通量，并建议将其作为康普顿支配的blazar的宽带SED的模型。
The broadband SEDs of blazars exhibit two broad spectral components, which in leptonic emission models are attributed to synchrotron radiation and SSC radiation of relativistic electrons. During high state phases, the high-frequency SSC component often dominates the low-frequency synchrotron component, implying that the inverse Compton SSC losses of electrons are at least equal to or greater than the synchrotron losses of electrons. The linear synchrotron cooling, usually included in radiation models of blazars, then has to be supplemented by the SSC cooling. Here, we present an analytical solution to the kinetic equation of relativistic electrons subject to the combined synchrotron and nonlinear synchrotron self-Compton cooling for monoenergetic injection. We calculate the time-dependent fluxes and time-integrated fluences resulting from monoenergetic electrons cooling via synchrotron and SSC, and suggest this as a model for the broadband SED of Compton-dominated blazars.
