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…
Topological Signatures of Heating and Dark Matter in the 21 cm Forest
Hayato Shimabukuro
We show that persistence-based topology of the 21 cm forest encodes information about Cosmic Dawn that is complementary to traditional amplitude- or correlation-based statistics. A…
Probing initial isocurvature perturbation with 21cm one-point statistics
Zhenfei Qin, Hayato Shimabukuro
Isocurvature perturbation--expected from multi-field inflation models--can leave unique signatures in the early Universe, but remain weakly constrained, especially on small scales.…
Analyzing the 21cm forest with Wavelet Scattering Transform: Insight into non-Gaussian features of the 21cm forest
Hayato Shimabukuro, Yidong Xu, Yue Shao
The 21cm forest, narrow absorption features in the spectra of high redshift radio sources caused by intervening neutral hydrogen, offers a unique probe of the intergalactic medium…
Square Kilometre Array Science Data Challenge 3a: foreground removal for an EoR experiment
A. Bonaldi, P. Hartley, R. Braun +179
We present and analyse the results of the Science data challenge 3a (SDC3a, https://sdc3.skao.int/challenges/foregrounds), an EoR foreground-removal community-wide exercise organis…
