Abstract:
The upstream regions of ICME shocks exhibit wave activity that can steepen the shock, scatter particles, and modify turbulence. In this study, we analyze multiple ICME shocks and their upstream regions. Using Fourier spectral methods, we identify wave activity in these regions. Our analysis shows that these waves interact resonantly with low-energy suprathermal particles on the order of 10 keV. We further characterize the nature of these waves.
