论文摘要
我们介绍了从积分/IBIS和SWIFT/BAT SURVEYS提取的软伽玛射线选择巨型射电星系（GRG）的最新消息；它包括8个新来源和一个候选对象。在新样本中，除了一个来源，显示了fr II无线电形态；唯一的例外是B21144+35B，它是FrI。这些对象均属于1型AGN光学类，并且在0.06-0.35范围内具有红移，而无线电尺寸为0.7至1 MPC。在这项研究中，我们首次介绍了两个从未像GRG一起讨论过的对象，并提出了一个新的候选人GRG。我们证实了X射线光度与其他软伽马射线的无线电芯发光度之间的相关性，并预期了由有效积聚提供的AGN。我们还证实了先前的结果，表明与核X射线发射相比，无线电裂片的光度相对较低。这支持了这样一个想法，即这些GRG的核现在比过去更强大，这与重新启动活动场景一致
We present an update on the sample of soft gamma-ray selected giant radio galaxies (GRGs) extracted from INTEGRAL/IBIS and Swift/BAT surveys; it includes 8 new sources and one candidate object. In the new sample all, but one source, display FR II radio morphologies; the only exception is B21144+35B which is an FR I. The objects belong to both type 1 and 2 AGN optical classes and have redshifts in the range 0.06-0.35, while the radio sizes span from 0.7 to 1 Mpc. In this study, we present for the first time two objects that were never discussed as GRGs before and propose a new candidate GRG. We confirm the correlation between the X-ray luminosity and the radio core luminosity found for other soft gamma-ray selected GRGs and expected for AGNs powered by efficient accretion. We also corroborate previous results that indicate that the luminosity of the radio lobes is relatively low compared with the nuclear X-ray emission. This supports the idea that the nucleus of these GRGs is now more powerful than in the past, consistent with a restarting activity scenario
