If gamma–ray bursts originate in dense stellar forming regions, the interstellar material can imprint detectable absorption features on the observed X–ray spectrum. Such features can be detected by existing and planned X–ray satellites, as long as the X–ray afterglow is observed after a few minutes from the burst. If the column density of the interstellar material exceeds ∼ 10 cm there exists the possibility to detect the Kα fluorescent iron line, which should be visible for more than one year… CONTINUE READING
