GRB 130427A: A Nearby Ordinary Monster
Science, 343, pp 48-51, 2014
Long-duration gamma-ray bursts (GRBs) are an extremely rare outcome ofthe collapse of massive stars and are typically found in the distantuniverse. Because of its intrinsic luminosity (L ˜ 3 ×1053 ergs per second) and its relative proximity (z = 0.34),GRB 130427A reached the highest fluence observed in the γ-rayband. Here, we present a comprehensive multiwavelength view of GRB130427A with Swift, the 2-meter Liverpool and Faulkes telescopes, and byother ground-based facilities, highlighting the evolution of the burstemission from the prompt to the afterglow phase. The properties of GRB130427A are similar to those of the most luminous, high-redshift GRBs,suggesting that a common central engine is responsible for producingGRBs in both the contemporary and the early universe and over the fullrange of GRB isotropic energies.
