摘要
BL Lac天体1ES 1011+496于2007年春被MAGIC发现于甚高能伽马射线。此前该源在不同波段很少被研究。因此2008年春组织了多波段（MWL）活动。除MAGIC外，MWL活动包括Metsahovi射电天文台、Bell和KVA光学望远镜以及Swift和AGILE卫星。MAGIC观测从2008年3月至5月，总计27.9小时，质量截断后剩余19.4小时。光变曲线未显示显著变率。微分VHE谱可用幂律函数描述。两结果均与发现时相似。Swift XRT观测揭示X射线耀发，特征为“越亮越硬”趋势，典型为高同步辐射峰BL Lac天体（HBL）。活动期间发现强光学变率，但无法得出光学与VHE伽马射线波段间关联的结论。同期SED显示同步辐射主导源，不同于先前基于非同时数据得出的结论，且很好由标准单区同步自康普顿模型描述。我们还进行了源分类研究。虽然活动期间光学和X射线数据展现HBL典型特征，我们基于档案数据建议1ES 1011+496实为中等与高同步辐射峰频率BL Lac天体间的边界情况。
