Wavelet-Scattering Signatures of Fuzzy Dark Matter in Simulated 21 cm Brightness-Temperature Maps

Hayato Shimabukuro, Shihang Liu, Bohua Li

We study the effect of fuzzy dark matter (FDM) on the multiscale morphology of simulated redshifted 21\,cm maps during Cosmic Dawn and the Epoch of Reionization. Using FDM-modified…
