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…
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…
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…
