Fermi-GST时代的最新多波长活动
Recent multi-wavelength campaigns in the Fermi-GST era
摘要：
自2008年以来，费米/LAT仪器已经为数量稳步增加的活动星系核提供了高时间分辨的伽马射线光谱和详细的变化曲线。为了详细研究活动星系核，费米/LAT数据必须与专门的地面和空间多频观测相结合。在这个框架下，费米AGN团队已经实现了一个详细的多波长活动计划，包括一个大型的厘米/毫米/亚毫米波段仪器套件。其中许多活动已经启动，通常是针对在燃烧州发现的放射源。我们在这里回顾了最近在三个这样的运动，即平谱射电类星体3C 279，窄线Seyfert 1 PMN J 0948 +0022和类星体3C 454.3期间获得的一些有趣的结果。
英文摘要：
Since 2008 the Fermi/LAT instrument has delivered highly time-resolved gamma-ray spectra and detailed variability curves for a steadily increasing number of AGN. For detailed AGN studies the Fermi/LAT data have to be combined with, and accompanied by, dedicated ground- and space-based multi-frequency observations. In this framework, the Fermi AGN team has realized a detailed plan for multi-wavelength campaigns including a large suite of cm/mm/sub-mm band instruments. Many of those campaigns have been triggered, often for sources detected in flaring states. We review here a few interesting results recently obtained during three such campaigns, namely for the flat-spectrum radio quasar 3C 279, the Narrow Line Seyfert 1 PMN J0948+0022 and quasar 3C 454.3.
