上下文PKS 1510 089是少数在甚高能（VHE，> 100 GeV）伽马射线波段发现的平谱射电类星体之一。目标。我们研究了PKS 1510 089在高γ射线状态下发射的宽带光谱和时间特性。方法.我们在2015年5月的长时间高伽马射线状态期间使用主要大气伽马成像切伦科夫（MAGIC）望远镜对PKS 1510 089进行了VHE伽马射线观测。为了进行宽带建模的源，我们还收集了同期的多波长数据，在无线电，红外，光学光度学和偏振，紫外线，X射线和GeV的伽马射线范围。根据VHE γ射线的状态，我们构造了一个两个周期的宽带谱能量分布（SED）。结果PKS 1510 089是MAGIC在长时间的高光学和伽马射线状态中进行的几天观测期间探测到的，首次显示出显着的VHE伽马射线变化。与2012年探测到的光源的光学和伽马射线高态类似，它伴随着光学偏振角的旋转和在无线电中观察到的新喷流成分的发射。然而，由于结分离时间的不确定性很大，与VHE伽马射线发射的关联不能牢固地建立。在耀斑期间的VHE波段的光谱形状是类似的源在以前的测量过程中获得的。观测到的通量变化第一次限制了VHE伽马射线发射区域的大小。我们模拟的宽带SED的框架内的外部康普顿的情况下，并讨论了可能的发射网站的多波长数据和替代的发射模型。
Context. PKS 1510 089 is one of only a few flat spectrum radio quasars detected in the very-high-energy (VHE, > 100 GeV) gamma-ray band. Aims. We study the broadband spectral and temporal properties of the PKS 1510 089 emission during a high gamma-ray state. Methods. We performed VHE gamma-ray observations of PKS 1510 089 with the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) telescopes during a long, high gamma-ray state in May 2015. In order to perform broadband modeling of the source, we have also gathered contemporaneous multiwavelength data in radio, IR, optical photometry and polarization, UV, X-ray, and GeV gamma-ray ranges. We construct a broadband spectral energy distribution (SED) in two periods, selected according to VHE gamma-ray state. Results. PKS 1510 089 was detected by MAGIC during a few day-long observations performed in the middle of a long, high optical and gamma-ray state, showing for the first time a significant VHE gamma-ray variability. Similarly to the optical and gamma-ray high state of the source detected in 2012, it was accompanied by a rotation of the optical polarization angle and the emission of a new jet component observed in radio. However, owing to large uncertainty on the knot separation time, the association with the VHE gamma-ray emission cannot be firmly established. The spectral shape in the VHE band during the flare is similar to those obtained during previous measurements of the source. The observed flux variability sets constraints for the first time on the size of the region from which VHE gamma rays are emitted. We model the broadband SED in the framework of the external Compton scenario and discuss the possible emission site in view of multiwavelength data and alternative emission models.
