A Chandra Search for X-Ray Jets in Redshift 6 Quasars

Abstract

We have searched for X-ray jets in the recent Chandra observations of three Sloan Digital Sky Survey (SDSS) quasars at redshift z ~ 6. All 3 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 jet-like 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 other X-ray jets at z<1. Deeper observations to confirm the interpretation as a jet will be practical.

Revised probabilities of X-ray detections, established 1030+0524 as extended and suggested gravitational lensing. Version accepted by ApJ Letters
