论文摘要
我们报告了两个高红移无线电类星体的扩展X射线发射的检测。在$ z $ = 3.208和$ z $ = 3.118的$ z $ = 3.208的J1405+0415时，在Chandra Snapshot调查中观察到了从Radio-Brightest类星体的完整样本中选择的VLA-First-First-First-First-First-Firp toct-First-Firp toct-First-Firp toctir-First-fore sublice unsuce和Sloan Digital Digital Sky调查。扩展的X射线发射位于连接核心与无线电结或热点的线路上，有利于解释X射线喷气机。从2--30 keV发出的推断的REST框架X射线照明将是订单10 $^{45} $ erg〜s $^{ - 1} $，如果同型发射，而没有相对论的光束。在宇宙微波背景（CMB）的反向康普顿散射的情况下，没有重合无线电的X射线喷气机可能很常见，并且由于（1+$ z $）$^4 $增加了CMB能量密度补偿（1+$ z $）$ z $ z $ $ z $ $ $ $^$^$^$^$^^^$^^$^^$^^$^^$^4 $ imin cmb supersion comby y imins comby的$^4 $也应易于检测到3.2以上。如果可以确认X射线，则它们将是数量X射线喷气机的第二个和第三个例子，而无需检测到潜在的连续无线电飞机。
We report the detection of extended X-ray emission from two high-redshift radio quasars. These quasars, J1405+0415 at $z$=3.208 and J1610+1811 at $z$=3.118, were observed in a Chandra snapshot survey selected from a complete sample of the radio-brightest quasars in the overlap area of the VLA-FIRST radio survey and the Sloan Digital Sky Survey. The extended X-ray emission is located along the line connecting the core to a radio knot or hotspot, favoring the interpretation of X-ray jets. The inferred rest frame jet X-ray luminosities from 2--30 keV would be of order 10$^{45}$ erg~s$^{-1}$ if emitted isotropically and without relativistic beaming. In the scenario of inverse Compton scattering of the cosmic microwave background (CMB), X-ray jets without a coincident radio counterpart may be common, and should be readily detectable to redshifts even beyond 3.2 due to the (1+$z$)$^4$ increase of the CMB energy density compensating for the (1+$z$)$^{-4}$ cosmological diminution of surface brightness. If these can be X-ray confirmed, they would be the second and third examples of quasar X-ray jets without detection of underlying continuous radio jets.
