摘要:

MAGIC自其科学运作开始以来一直在执行光学触发的机会目标观测。耀斑的警报来自Tuorla Blazar监测计划,该计划于2002年开始对候选TeV blazar进行光学监测,目前已收集了60多个blazar长达8年的数据。这些ToO观测导致发现了五个新的VHE伽马射线发射耀变体(S5 0716+714,1ES 1011+496,Mrk 180,ON 325和B3 2247+381)。此外,BL Lac和3C 279的部分发现是在高光学状态下完成的。在这方面的贡献,我们提出了一个详细的分析,然后比较魔术观测相同的来源的光学光变曲线。我们的目标是回答这样一个问题:“耀变体中的光学和VHE射线高态之间是否存在联系,或者我们只是运气好?”"

英文摘要:

MAGIC has been performing optically triggered Target of Opportunity observations of flaring blazars since the beginning of its scientific operations. The alerts of flaring blazars originate from Tuorla Blazar Monitoring Programme, which started the optical monitoring of candidtate TeV blazars in 2002 and has now collected up to eight years of data on more than 60 blazars. These ToO observations have resulted in the discovery of five new VHE gamma-ray emitting blazars (S5 0716+714, 1ES 1011+496, Mrk 180, ON 325 and B3 2247+381). In addition part of the discovery of BL Lac and the discovery of 3C 279 was made during a high optical state. In this contribution we present a detailed analysis of the optical light curves which are then compared to MAGIC observations of the same sources. We aim to answer the question: "Is there a connection between optical and VHE -ray high states in blazars or have we just been lucky?"
