摘要
我们基于在 2009 年 3 月 15 日至 2009 年 8 月 1 日多仪器联合观测活动期间收集的数据集，对 BL Lac 天体 Mrk 501 进行了广泛研究，该数据集除其他仪器外还包括 MAGIC、VERITAS、Whipple 10-m、Fermi-LAT、RXTE、Swift、GASP-WEBT 和 VLBA。我们发现分数变率随能量增加，而在所获得的数据集中未发现流量变化的显著波段间相关性。甚高能（>100 GeV，VHE）伽马射线辐射的较高变率以及其与 X 射线辐射缺乏相关性表明，产生 VHE 伽马射线的最高能电子对 ~1 keV 辐射没有主导贡献。另一种可能是，除了来自同步自康普顿（SSC）情景的贡献外，还存在一个变化剧烈的组分贡献于 VHE 伽马射线辐射。遵循专门的网格扫描策略探测 SSC 模型参数空间，使得能够检验广泛范围的模型，并提供了对单个模型参数中模型-数据吻合简并性的研究。我们发现所探测的单区与双区 SSC 情景均存在某种简并，多个模型参数组合产生相似的模型-数据吻合度，且某些参数比其他参数约束更好。SSC 模型网格扫描显示，2009 年 5 月 22 日左右的耀发活动无法用单区 SSC 情景充分建模，而可用双独立区 SSC 情景恰当描述。观测到的电矢量偏振角旋转与 2009 年 5 月 1 日的伽马射线耀发重合，类似于先前报道的低频峰耀变体情况，从而表明具有不同喷流性质的耀变体的耀发机制存在许多相似性。
