Slow radio burst

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.) Webb21 jan. 2024 · These "slow"radio bursts (SRBs) would have broader widths and lower flux densities due to the smaller Doppler factor involved. We derive two "closure relations"to …

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.
