甚高能量(Vhe；E&GT；100GeV)Blaazar Markarian501(MRK 501)有着研究极端光谱变化的历史，是研究活动星系核喷流内部物理过程的优秀实验室。然而，由于MRK 501的低光度，在其静止状态下，很少有详细的多波长研究。2009年3月协调了对MRK501的短期多波长研究，重点是利用铃鹿X射线卫星进行的多天观测，并包括来自VERITAS、MAGIC和费米伽马射线空间望远镜的γ射线数据，目的是为静止状态下的MRK501提供采样良好的多波长基线测量。将这些静态观测的结果与1997年4月16日的历史极端爆发进行比较，目的是检查两种状态之间光谱能量分布(SED)的可变性。导出的宽带SED呈现出特征的双峰分布。我们发现，X射线峰值在两个流态之间移动了超过两个数量级的光子能量，而VHe峰值变化很小。VHE峰的有限移动可以用向Klein-Nishina(KN)机制的转变来解释。同步加速器自康普顿模型与数据进行了匹配，并探索了隐含的KN效应。
The very high energy (VHE; E > 100 GeV) blazar Markarian 501 (Mrk 501) has a well-studied history of extreme spectral variability and is an excellent laboratory for studying the physical processes within the jets of active galactic nuclei. However, there are few detailed multiwavelength studies of Mrk 501 during its quiescent state, due to its low luminosity. A short-term multiwavelength study of Mrk 501 was coordinated in 2009 March, focusing around a multi-day observation with the Suzaku X-ray satellite and including γ-ray data from VERITAS, MAGIC, and the Fermi Gamma-ray Space Telescope with the goal of providing a well-sampled multiwavelength baseline measurement of Mrk 501 in the quiescent state. The results of these quiescent-state observations are compared to the historically extreme outburst of 1997 April 16, with the goal of examining variability of the spectral energy distribution (SED) between the two states. The derived broadband SED shows the characteristic double-peaked profile. We find that the X-ray peak shifts by over two orders of magnitude in photon energy between the two flux states while the VHE peak varies little. The limited shift in the VHE peak can be explained by the transition to the Klein–Nishina (KN) regime. Synchrotron self-Compton models are matched to the data and the implied KN effects are explored.
