标题： Blazars: the gamma-ray view of AGILE

摘要： 自2007年4月发射以来，AGILE卫星利用其伽马射线成像探测器（GRID）检测到多个具有高显著性的耀变体：3C 279、3C 454.3、PKS 1510-089、S5 0716+714、3C 273、W Comae、Mrk 421和PKS 0537-441。此外，AGILE还能够迅速响应耀变体在其他波段上的活动状态变化，并及时向其他望远镜发出伽马射线流量变化的警报。因此，我们得以从其他天文台（如斯皮策、Swift、RXTE、Suzaku、INTEGRAL、MAGIC、VERITAS）以及通过WEBT和REM项目的射电至光学覆盖范围内获得多波段数据。这种广泛的多频率观测使我们有机会研究这些源从射电到伽马射线能段的谱能量分布，并探讨导致其辐射的不同机制。本文综述了AGILE在这些伽马射线耀变体上的研究成果及相关多波段数据。 显示英文摘要

摘要： Since its launch in April 2007, the AGILE satellite detected with its Gamma-Ray Imaging Detector (GRID) several blazars at high significance: 3C 279, 3C 454.3, PKS 1510-089, S5 0716+714, 3C 273, W Comae, Mrk 421 and PKS 0537-441. Moreover, AGILE was able both to rapidly respond to sudden changes in blazar activity state at other wavelengths and to alert other telescopes quickly in response to changes in the gamma-ray fluxes. Thus, we were able to obtain multiwavelength data from other observatories such as Spitzer, Swift, RXTE, Suzaku, INTEGRAL, MAGIC, VERITAS, as well as radio-to-optical coverage by means of the GASP Project of the WEBT and REM. This large multifrequency coverage gave us the opportunity to study the Spectral Energy Distribution of these sources from radio to gamma-rays energy bands and to investigate the different mechanisms responsible for their emission. We present an overview of the AGILE results on these gamma-ray blazars and the relative multifrequency data.
