21cm forest probes on the axion dark matter in the post-inflationary Peccei-Quinn symmetry breaking scenarios
Hayato Shimabukuro, Kiyotomo Ichiki, Kenji Kadota
We study the future prospects of the 21cm forest observations on the axion-like dark matter when the spontaneous breaking of the global Peccei-Quinn (PQ) symmetry occurs after the…

Constraints on nature of ultra light dark matter particles with 21cm forest
Hayato Shimabukuro, Kiyotomo Ichiki, Kenji Kadota
The ultra-light scalar fields can arise ubiquitously, for instance, as a result of the spontaneous breaking of an approximate symmetry such as the axion and more generally the axio…
