Question

Quizplus · Accepted Answer

Gamma-ray bursts (GRBs) are known for their afterglows at various wavelengths, including optical and radio, which can last from hours to several weeks following the initial burst. This afterglow is due to the interaction of the ejected material with the surrounding medium, causing a shock wave that emits across the electromagnetic spectrum.
