Deep learning-driven likelihood-free parameter inference for 21-cm forest observations by Tian-Yang Sun, Yue Shao, Yichao Li, Yidong Xu, He Wang, Xin Zhang

“…Abstract The hyperfine structure absorption lines of neutral hydrogen in high-redshift radio spectra, known as the 21-cm forest, have been demonstrated through simulations as a powerful probe of small-scale structures governed by dark matter (DM) properties and the thermal history of intergalactic medium (IGM). …”
