Webb22 nov. 2024 · These enigmatic events are short (a few milliseconds), super energetic (~10x the luminosity of the Sun) bursts of radio emission originating from other galaxies (although this Astrobite covers an FRB-like burst from within our own galaxy). While the first FRB was discovered in 2007, over 3000 of these events have now been detected.

Webb10 sep. 2024 · The radio burst near 50 MHz of a 5–10 MHz width at the beginning of the injection pulse is a rapid drift from lower to higher frequencies within the spectrograph sweeping time of 20 ms. The spectral maxima (bulges) are centered at half-integral harmonics of the electron gyrofrequency, f s ≈ ( s + 1 2 ) f c e , with integers s ≥ 20 to ≈ 30. crystal ball cafe

Another mysterious radio burst in space is repeating a pattern

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. Webb16 nov. 2024 · The CRAFT data revealed neither a persistent, compact radio source before the burst, nor a slowly varying radio afterglow after the burst. What does this mean? The lack of detectable afterglow for FRB 191001 alone doesn’t yet rule out any formation scenarios — but it does demonstrate that the afterglow was either fainter than our …
