Extended Data Fig. 4: Power spectral density of the foreshock and magnetosheath fluctuations observed by MMS on 14 February 2020.
From: Transmission of foreshock waves through Earth’s bow shock
Power spectral density of the total magnetic field fluctuations calculated for the intervals marked by the vertical lines in Fig. 4 in the foreshock (black) and in the magnetosheath (red). The vertical dashed lines indicate the predicted foreshock wave frequency for each interval from the Takahashi et al.9 formula.
