摘要：

If X-rays observed from any extragalactic radio jets are due to inverse Compton scattering on the cosmic microwave background (CMB) radiation, then such a source will be detectable with the same surface brightness anywhere in the more distant universe. Chandra observations imply that such systems do exist, and will therefore serve as Cosmic Beacons out to the redshift at which they form.
