摘要：

We have searched for X-ray jets in the recent Chandra observations of three Sloan Digital Sky Survey (SDSS) quasars at redshift z approximate to 6. All three quasars were detected in X-rays in these relatively short observations. SDSS 1030+0524 is not consistent with a point source and may be a gravitationally lensed system. We find a possible jetlike feature 23" from the quasar SDSS 1306+0356. We can explain the emission by inverse Compton scattering off the cosmic microwave background, assuming that the intrinsic properties of the system are similar to X-ray jets at z<1. Deeper observations to investigate the jet interpretation will be practical.
