论文摘要
我们介绍了有关从SDS，第一目录和XMM-Newton档案中的交叉匹配构建的无线电检测的类星体样本的X射线发射的研究。还组装了没有第一次无线电检测的无线电标准类星体样本以进行比较。我们构建了在RESIT框架上构造的光学和X射线复合光谱$ 4215 \，\rmÅ$（或$ 2200 \，\rmÅ$），用于radio-loud quasars（rlqs）和badio-z \ le3.2 $的radio-loud quasars（rlq）和doadio-quiet quasars（rlq）和doady-quiet quasars（rqqs），并具有匹配的x-ray um lum lum lum lum redshift and redshift of condshift and redshift of redshift。虽然RLQ的光学复合谱与RQQ相似，但我们发现RLQ的X射线复合频谱比RQQ具有更高的X射线复合谱，这与先前的文献研究一致。通过将无线电检测的类星体分为无线电响度箱，我们发现X射线复合光谱通常会随着无线电响度的增加而更高。此外，在光学到X射线光谱指数和无线电响度之间发现了显着的相关性，并且在无线电检测的类星体中的无线电，X射线照明和无线电响度之间存在统一的多相关。这些结果可能可以用电晕喷气机模型来解释，在该模型中，电晕和JET是直接相关的。
We present the study on the X-ray emission for a sample of radio-detected quasars constructed from the cross-matches between SDSS, FIRST catalogs and XMM-Newton archives. A sample of radio-quiet SDSS quasars without FIRST radio detection is also assembled for comparison. We construct the optical and X-ray composite spectra normalized at rest frame $4215\,\rm Å$ (or $2200\,\rm Å$) for both radio-loud quasars (RLQs) and radio-quiet quasars (RQQs) at $z\le3.2$, with matched X-ray completeness of 19\%, redshift and optical luminosity. While the optical composite spectrum of RLQs is similar to that of RQQs, we find that RLQs have higher X-ray composite spectrum than RQQs, consistent with previous studies in the literature. By dividing the radio-detected quasars into radio loudness bins, we find the X-ray composite spectra are generally higher with increasing radio loudness. Moreover, a significant correlation is found between the optical-to-X-ray spectral index and radio loudness, and there is a unified multi-correlation between the radio, X-ray luminosities and radio loudness in radio-detected quasars. These results could be possibly explained with the corona-jet model, in which the corona and jet are directly related.
