Highest-energy light from a gamma-ray burst ever

It has been decades since the discovery of the first gamma-ray burst, yet some of their fundamental traits remain unclear. An international team of researchers, including two astrophysicists from the George Washington University, Chryssa Kouveliotou and Alexander van der Horst, now has taken the next step in understanding the physical processes at work during these events with a recent discovery published in the journal Nature on November, 20/

The researchers observed a gamma-ray burst with an afterglow that featured the highest energy photons ever detected in a burst.

On January, 14, 2019, researchers detected a burst labeled GRB 190114C. The discovery triggered an extensive campaign of observations across the electromagnetic spectrum using more than 20 observatories and instruments around the world. This collaborative effort allowed an international team to gather an unprecedented level of information about GRB 190114C, capturing the evolution of the gamma-ray burst afterglow emission across 17 orders of magnitude in energy.
