基于磁场重联的Blazar辐射模型成功地再现了许多观测到的光谱和时间特征，包括短持续时间的发光耀斑事件。等离子体团是重联层撕裂不稳定性的自洽副产物，是耀变体辐射的主要来源。相对论重联的动力学模拟表明，等离子体团的特征是其辐射粒子和磁场之间的粗略能量均分。这是等离子体团占主导地位的发射模型解释BL Lac天体观测到的康普顿比的明显缺陷背后的主要原因。在这里，我们证明了等离子体团之间的辐射相互作用，这一直被忽视，到目前为止，可以帮助缓解这一矛盾。我们发现，大，缓慢移动的等离子体团发射的光子可以是一个潜在的重要来源的软光子，然后向上散射，通过逆康普顿，由小的快速移动，相邻的等离子体团。这种等离子体团间的康普顿散射过程可以自然地发生在整个重联层中，在BL Lac源内的那些短而明亮的等离子体团动力耀斑中观察到的康普顿比增加，同时保持辐射粒子和磁场之间的能量均分。
Blazar emission models based on magnetic reconnection succeed in reproducing many observed spectral and temporal features, including the short-duration luminous flaring events. Plasmoids, a self-consistent by-product of the tearing instability in the reconnection layer, can be the main source of blazar emission. Kinetic simulations of relativistic reconnection have demonstrated that plasmoids are characterized by rough energy equipartition between their radiating particles and magnetic fields. This is the main reason behind the apparent shortcoming of plasmoid-dominated emission models to explain the observed Compton ratios of BL Lac objects. Here, we demonstrate that the radiative interactions among plasmoids, which have been neglected so far, can assist in alleviating this contradiction. We show that photons emitted by large, slow-moving plasmoids can be a potentially important source of soft photons to be then upscattered, via inverse Compton, by small fast-moving, neighbouring plasmoids. This interplasmoid Compton scattering process can naturally occur throughout the reconnection layer, imprinting itself as an increase in the observed Compton ratios from those short and luminous plasmoid-powered flares within BL Lac sources, while maintaining energy equipartition between radiating particles and magnetic fields.
