Webb28 mars 2024 · The brightest burst ever seen, known as GRB 221009A, was first detected on Oct. 9, 2024 by gamma-ray and X-ray telescopes. The likely supernova that caused the burst was 2.4 billion light-years... WebbElectrons become excited and, as a result of the polarized conditions, start to rotate about magnetic field lines, generating radio waves. This happens as the wave of material makes more and more impacts, which causes the shock wave to slow down.

It's possible FRB 121102 may have a slowly rotating magnetar as its source, but it's not clear. countrified hicks

"Webb28 feb. 2024 · As the shock presses outward, the electrons inside gyrate around along magnetic field lines, and that motion produces a burst of radio waves. That signal then shifts from higher to lower frequencies as the shock slows. (And presumably, far away and eons later, Earth’s astronomers get a very exciting email alert from radio telescopes.)
