An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
An Extremely Luminous Panchromatic Outburst from the Nucleus of a Distant Galaxy
Variable X-ray and gamma-ray emission is characteristic of the most extreme physical processes in the Universe, and studying the sources of these energetic photons has been a major driver in astronomy for the past 50 years. Here we present multiwavelength observations of a unique gamma-ray selected transient, discovered by Swift, …
