我们讨论了在3-30红移范围内伽马暴余辉的x射线通量,包括星系间He II吸收的影响。我们指出,强x射线线可能在触发后几分钟开始的爆发余辉中局部形成。这可以为第一代大质量恒星形成时的红移提供独特的x射线距离指示器。
We discuss the X-ray flux of gamma-ray burst afterglows at redshifts in the range 3-30, including the effects of the intergalactic He II absorption. We point out that strong X-ray lines may form locally in burst afterglows starting minutes after the trigger. This can provide distinctive X-ray distance indicators out to the redshifts at which the first generation of massive stars form.
