我们报告在红移为4.320 +/- 0.005的x射线选择的准恒星物体（QSO）的发现。这是已知最遥远的x射线选择物体，也是已知第八遥远的QSO。在红移大于4时，该QSO的性质与其他QSO非常相似。这个天体的x射线发现，以及高红移星系团的发现，表明目前的x射线调查正在达到与其他方法竞争的深度。
We report the discovery of an x-ray selected Quasi-Stellar Objects (QSO) at a redshift of 4.320 +/- 0.005. This is the most distant x-ray selected object known, and it is the eighth most distant QSO known. The properties of this QSO are very similar to other QSOs at redshifts greater than 4. The x-ray discovery of this object, and that of high redshift clusters of galaxies, shows that present x-ray surveys are reaching depths competitive with other methods.
