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…

Constraining fuzzy dark matter with the 21-cm power spectrum from Cosmic Dawn and Reionization
Shihang Liu, Yilin Liu, Bowen Peng +4
The 21-cm signals from Cosmic Dawn and the Epoch of Reionization contain valuable information on cosmological structure formation dominated by dark matter. Measurements of the 21-c…
