| Figure 4. The Fourier and wavelet power spectrum of the 1D velocity field for baryonic fluid. The left vertical axis is for the Fourier power spectrum, and the right axis is for the wavelet power spectrum. The wavelet energy spectrum is also shown for comparison. The data is taken from the IllustrisTNG simulation. |
