High-Redshift Signatures from the Cosmic Dawn and the Epoch of Reionization
Rennan Barkana, Oliver Basquette, Ankita Bera +22
In this chapter, we provide a comprehensive overview of the astrophysical and cosmological processes that shape the 21-cm signal during Cosmic Dawn and the Epoch of Reionization. W…
21 cm forest one-dimensional power spectrum as an indirect probe of dark matter particles and primordial black holes
Meng-Lin Zhao, Yue Shao, Sai Wang +1
Understanding the nature of dark matter (DM) particles remains a pivotal challenge in modern cosmology. Current cosmological research on these phenomena primarily utilizes cosmic m…
Prospects for probing dark matter particles and primordial black holes with the Hongmeng mission using the 21 cm global spectrum at cosmic dawn
Meng-Lin Zhao, Sai Wang, Xin Zhang
Probing dark matter particles and primordial black holes remains a pivotal challenge in modern cosmology. Exotic energy injections from dark matter annihilation, decay, and PBH Haw…
Analytical modeling of the one-dimensional power spectrum of 21-cm forest based on a halo model method
Yue Shao, Tian-Yang Sun, Meng-Lin Zhao +1
The 21-cm forest, composed of spectral absorption features from high-redshift background radio sources, provides a unique probe for studying small-scale structures during the epoch…
