Probing the cosmic reionization history and local environment of gamma-ray bursts through radio dispersion
Probing the cosmic reionization history and local environment of gamma-ray bursts through radio dispersion
We discuss the effect of dispersion delay due to intervening ionized media in the radio emission of gamma-ray bursts (GRBs). For high-redshift GRBs (z≳ 3), the ionized intergalactic medium (IGM) should be the dominant source of dispersion without substantial local or foreground contamination, offering a unique probe of the cosmic …
