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…
Predicting 21cm-line map from Lyman emitter distribution with Generative Adversarial Networks
Shintaro Yoshiura, Hayato Shimabukuro, Kenji Hasegawa +1
The radio observation of 21\,cm-line signal from the Epoch of Reionization (EoR) enables us to explore the evolution of galaxies and intergalactic medium in the early universe. How…
Estimation of HII Bubble Size Distribution from 21cm Power Spectrum with Artificial Neural Networks
Hayato Shimabukuro, Yi Mao, Jianrong Tan
The bubble size distribution of ionized hydrogen regions probes the information about the morphology of \HII\ bubbles during the reionization. Conventionally, the \HII\ bubble size…
