论文摘要
本文的目的是研究FR II射电星系4C 14.11的通量和光谱指数分布。我们专注于在裂片上及其热点上的通量和光谱指数的分布。为此，我们使用了1450和8440 MHz给出的该射电星系的公开观察结果。特别是，我们使用了Leahy的电台发射双重无线电源的地图集，曼彻斯特的Jodrell Bank Bank Bank Bank Center以及NASA/IPAC/IPAC Extagalactic数据库。我们发现，非热（同步）辐射在裂片区域占主导地位。在光谱指数中，热点和其余叶之间的区别要比通量小得多。我们还发现，在两个裂片的内部，光谱指数$α$平均平均扁平，显着高于1.2，这表明4C 14.11是旧的AGN。
The goal of this paper is to investigate the flux and spectral index distribution of FR II radio galaxy 4C 14.11. We focused on the distribution of flux and spectral indices over the lobes, as well as in their hot spots. For that purpose, we used publicly available observations of this radio galaxy given at 1450 and 8440 MHz. Particularly, we used Leahy's Atlas of radio-emitting double radio sources, Jodrell Bank Centre for Astrophysics in Manchester, as well as NASA/IPAC Extragalactic Database. We found that the non-thermal (synchrotron) radiation dominates over the areas of the lobes. Distinction between hot spots and rest of the lobes are much smaller in the spectral index than in the flux. We also found that over the inner parts of both lobes, spectral index $α$ is flat in average and significantly higher than 1.2, indicating that 4C 14.11 is old AGN.
