Monitoring the radio spectra of selected blazars in the Fermi-GST era. The Effelsberg 100 m telescope covering the cm band
摘要：
从射电到TeV的光谱能量分布变化的分析是一个强有力的工具，在调查的动力学，物理和结构演化发生在最奇特的风味的活动星系，耀变体。特别是，{ \sl Fermi-GST}的存在为这些研究提供了前所未有的质量的$γ$射线数据提供了独特的机会。在这里，我们介绍了一个监测计划，自2007年1月以来一直在Effelsberg 100米望远镜上运行，支持从无线电到红外波段的广泛多频合作设施。在2.64 GHz和43 GHz之间每月观测到61个选定的耀变体。初步算例表明，标定精度优于百分之几。
英文摘要：
The analysis of the spectral energy distribution variability at frequencies from radio to TeV is a powerful tool in the investigation of the dynamics, the physics and the structure evolution occurring in the most exotic flavour of active galaxies, the blazars. In particular, the presence of {\sl Fermi-GST} is providing a unique opportunity for such studies delivering $γ$-ray data of unprecedented quality. Here we introduce a monitoring program that has been running at the Effelsberg 100m telescope since January 2007, underpinning a broad multi-frequency collaboration of facilities that cover the band from radio to infrared. Sixty one selected blazars are observed monthly between 2.64 GHz and 43 GHz. The calibration accuracy is better than a few percent as it is demonstrated with some preliminary examples.
