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.

"Webb19 okt. 2024 · A possible reprieve here is that the slowest magnetar known has a spin of about once per 6.5 hours (over 24,000 seconds), so a periodic signal from such a slow one would not have been seen by FAST. It's possible FRB 121102 may have a slowly rotating magnetar as its source, but it's not clear. " - Slow radio burst
