论文摘要

我们探讨了类星体的X射线光度函数的演变以及X射线与2500Å$ \,$ Ultraviolet Luminosities的固有相关性,并利用了以前的作品中验证的技术,并在$ 0 <z <z <z <5 $ 0 <z <z <z <5 $中检测到的4000多个类星体样本。我们发现,与其他波段相比,与其他波段相比,类星体的总X射线发光度的进化明显较小。 We then determine that the best fit intrinsic power law correlation between the X-ray and ultraviolet luminosities, of the form $L'_{\rm X} \propto ({L'_{\rm UV}})^γ$, is $γ=0.28\pm$0.03, and we derive the luminosity function and density evolution in the X-ray band.我们讨论了这些结果对类星体系统模型的含义。

We explore the evolution of the X-ray luminosity function of quasars and the intrinsic correlation between the X-ray and 2500Å$\,$ ultraviolet luminosities, utilizing techniques verified in previous works and a sample of over 4000 quasars detected with Chandra and XMM-Newton in the range $0<z<5$. We find that quasars have undergone significantly less evolution with redshift in their total X-ray luminosity than in other wavebands. We then determine that the best fit intrinsic power law correlation between the X-ray and ultraviolet luminosities, of the form $L'_{\rm X} \propto ({L'_{\rm UV}})^γ$, is $γ=0.28\pm$0.03, and we derive the luminosity function and density evolution in the X-ray band. We discuss the implications of these results for models of quasar systems.
