人们普遍认为，在许多活动星系中所有可到达的能带上检测到的强而可变的辐射是由指向我们视线附近的相对论性、多普勒增强的射流产生的。然而，发射区的大小以及该区域相对于中心超大质量黑洞的位置却鲜为人知，估计范围从光时到光年甚至更多。在这里，我们报告了伽马射线耀斑与光学偏振角的巨大变化的一致性。这为光学和伽马射线发射区域的共空间性提供了证据，并表明了高度有序的射流磁场。结果还需要发射区的非轴对称结构，这意味着射流内发射材料的轨迹是弯曲的，耗散区域距离黑洞相当远，引力半径约为 10^5。
It is widely accepted that strong and variable radiation detected over all accessible energy bands in a number of active galaxies arises from a relativistic, Doppler-boosted jet pointing close to our line of sight. The size of the emitting zone and the location of this region relative to the central supermassive black hole are, however, poorly known, with estimates ranging from light-hours to a light-year or more. Here we report the coincidence of a gamma-ray flare with a dramatic change of optical polarization angle. This provides evidence for co-spatiality of optical and gamma-ray emission regions and indicates a highly ordered jet magnetic field. The results also require a non-axisymmetric structure of the emission zone, implying a curved trajectory for the emitting material within the jet, with the dissipation region located at a considerable distance from the black hole, at about 10^5 gravitational radii.
