Distributions of the wave spectral magnetic energy densities log10(∣Bzk(kx, ky)∣2) emitted at the frequency ωkωp, for (a) ΔN = 0 (upper row) and (b) ΔN = 0.05 (bottom row). The initial density distribution is given in Figure 1 of Krafft & Savoini (2021). The “smaller” box with size ﹩{L}_{x}\times {L}_{y}=1448\times 1448{\lambda }_{D}^{2}﹩ is used. The spectra are given at times ωpt = 145, 2020, 3100, 6430, and 7960. The same color bar holds for all plots. All variables are normalized.
