论文摘要
我们介绍了属于第20个剑桥修订的目录（3CR）的九个无线电来源，在20周期中以$ Chandra $在1.5到2.5之间的$ Chandra $中观察到。这项研究完成了3CR $ Chandra $快照调查，因此保证了迄今为止确定的所有3CR来源的X射线覆盖范围。该样本列出了两个紧凑的陡峭光谱源，四个射电星系和三个类星体。我们从所有原子核中检测到X射线排放，唯一的3C 326.1和3C 454.1和来自9个源的无线电裂片的9个来源的置信度大于$ \ sim $ 5 $σ$。我们测量了软（0.5-1 keV），培养基（1-2 keV）和硬（2-7 keV）X射线带中所有核和叶的X射线通量和亮度。由于发现的X射线扩展发射在所有情况下都与无线电结构相吻合，因此其起源可能是由于无线电裂片中发生的宇宙微波背景（IC/CMB）的反向造成的。
We present the analysis of nine radio sources belonging to the Third Cambridge Revised catalog (3CR) observed with $Chandra$ during Cycle 20 in the redshift range between 1.5 and 2.5. This study completes the 3CR $Chandra$ Snapshot Survey thus guaranteeing the X-ray coverage of all 3CR sources identified to date. This sample lists two compact steep spectrum sources, four radio galaxies and three quasars. We detected X-ray emission from all nuclei, with the only exception of 3C 326.1 and 3C 454.1 and from radio lobes in 6 out of 9 sources at level of confidence larger than $\sim$5$σ$. We measured X-ray fluxes and luminosities for all nuclei and lobes in the soft (0.5 - 1 keV), medium (1 - 2 keV) and hard (2 - 7 keV) X-ray bands. Since the discovered X-ray extended emission is spatially coincident with the radio structure in all cases, its origin could be due to Inverse Compton scattering of the Cosmic Microwave Background (IC/CMB) occurring in radio lobes.
