Dynamic Spectrum of the FRB (IMAGE) California Institute of Technology Caption The intensity of FRB 150807 at different radio frequencies or colors -- red corresponds to lower frequencies and blue to higher frequencies. The x-axis is time. The fine structure in the burst is the scintillation or twinkling--the rays interfere constructively and destructively differently at different frequencies. This pattern provides insights into the turbulence in plasma towards the burst. Credit Courtesy of V.
