TL;DR: A comprehensive multiwavelength view of GRB 130427A with Swift, the 2-meter Liverpool and Faulkes telescopes, and by other ground-based facilities is presented, highlighting the evolution of the burst emission from the prompt to the afterglow phase and suggesting that a common central engine is responsible for producing GRBs in both the contemporary and the early universe.
