Using various telescopes, an international team of astronomers has performed multi-wavelength observations of a recently identified gamma-ray burst source designated GRB 250416C. Results of the observational campaign, published April 23 on the v pre-print server, could help us better understand the nature of GRB 250416C and gamma-ray bursts in general.

Gamma-ray bursts (GRBs) are the most powerful electromagnetic explosions in the universe, usually caused by the destruction of massive stars. In general, they are observed as bursts of highly energetic gamma rays lasting from less than a second to several minutes.
