Extended Data Fig. 3: Measurement of the scintillation bandwidth in the autocorrelation function (ACF) of each of the five bursts from FRB 20200120E.
From: Burst timescales and luminosities as links between young pulsars and fast radio bursts
Sub-figure a shows the time-averaged frequency ACF from Extended Data Figure 2 after subtracting the Gaussian fit (black). The Lorentzian fit to the central component is shown by the colored line. The burst name is shown in the top left of each panel, and the measured scintillation bandwidth (defined as the half-width at half-maximum of the Lorentzian80) is shown in the top right of each panel. Sub-figure b shows a colormap of the expected scattering timescale at 1.4 GHz as a function of Galactic longitude and latitude, from the NE2001 Galactic electron density model30. The sky positions of both FRB 20200120E and FRB 20180916B are shown by the black cross and white plus, respectively.
