摘要:

由于短的占空比和观测时间的限制,亮TeV(E>100 GeV)耀变体的研究大多局限于耀斑发作或相当短(几天到几周)的多波长运动。与此同时,对这些天体的长期研究对于更全面地了解耀变体现象和限制有关喷流物理学的理论模型至关重要。只有无偏的长期研究是足够的耀斑状态的概率的确定和估计TeV耀斑状态和其他波段或可观测量,如中微子事件之间可能的相关性的统计意义。定期观测还提供了触发多波长ToO观测起源于TeV波段。这些特别需要识别和研究孤儿TeV耀斑,即在其他波段没有对应物的耀斑。在2007/2008年,MAGIC望远镜定期监测了三个TeV耀变体:Mrk 501,Mrk 421和1 ES 1959+650。我们提出了这些观测的初步结果,包括测量的光变曲线和相关性研究VHE伽马射线和X射线和VHE伽马射线和光学R-波段的Mrk 421。

英文摘要:

Because of the short duty-cycles and observation-time constraints, studies of bright TeV (E>100 GeV) blazars are mostly restricted to flaring episodes or rather short (days to few weeks) multiwavelength campaigns. At the same time, long-term studies of these objects are essential to gain a more complete understanding of the blazar phenomenon and to constrain theoretical models concerning jet physics. Only unbiased long-term studies are adequate for the determination of flaring state probabilities and for estimating the statistical significance of possible correlations between TeV flaring states and other wavebands or observables, such as neutrino events. Regular observations also provide triggers for multiwavelength ToO observations originating from the TeV waveband. These are particularly needed to identify and study orphan TeV flares, i.e. flares without counterparts in other wavebands. In 2007/8 the MAGIC telescope has monitored three TeV blazars on a regular basis: Mrk 501, Mrk 421, and 1ES 1959+650. We present preliminary results of these observations including the measured light curves and a correlation study for VHE gamma-rays and X-rays and VHE gamma-rays and optical R-band for Mrk 421.
