摘要:

我们报告的结果,从一个密集的多波长运动的中频峰值BL Lacertae对象W COM(z = 0.102)在一个非常高的能量γ射线发射在2008年6月的强烈爆发。VERITAS在2008年6月7日至8日探测到了非常高能量的伽马射线信号,通量F(> 200 GeV)=(5.7 +-0.6 x10 ^-11 cm-2s-1),比VERITAS在2008年3月发现W Com的伽马射线发射时亮约三倍。VERITAS在能量超过200 GeV时首次探测到这一耀斑,随后又进行了高能伽马射线(AGILE,E> 100 MeV)、X射线(Swift和XMM-Newton)和紫外线观测,并通过GASP-WEBT联合会和其他观测站进行了地面光学和无线电监测。在这里,我们描述的多波长数据,并得出光谱能量分布(SED)的来源,从同期的数据采取整个耀斑。

英文摘要:

We report results from an intensive multiwavelength campaign on the intermediate-frequency-peaked BL Lacertae object W Com (z=0.102) during a strong outburst of very high energy gamma-ray emission in June 2008. The very high energy gamma-ray signal was detected by VERITAS on 2008 June 7-8 with a flux F(>200 GeV) = (5.7+-0.6)x10^-11 cm-2s-1, about three times brighter than during the discovery of gamma-ray emission from W Com by VERITAS in 2008 March. The initial detection of this flare by VERITAS at energies above 200 GeV was followed by observations in high energy gamma-rays (AGILE, E>100 MeV), and X-rays (Swift and XMM-Newton), and at UV, and ground-based optical and radio monitoring through the GASP-WEBT consortium and other observatories. Here we describe the multiwavelength data and derive the spectral energy distribution (SED) of the source from contemporaneous data taken throughout the flare.
