- 요약The ΛCDM model has been successfully matched major observations of the Universe while certain critical questions are unsolved. Several novel and powerful cosmological probes, such as galaxy survey of Roman Space Telescope, Lyman-α forest in DESI and 21 cm intensity mapping in HERA and future PUMA, are on the track of construction or collecting data about the Universe through their unique detective ability. While these experiments aim to push the boundary of observations in terms of precision and scope, it is very critical to properly understand the thermal and kinetic properties of the intergalactic medium since they could be sources of systematic errors. In Chapter 2, I explored the impacts streaming velocity between dark matter and baryonic matter on the large-scale structure measurement in 21 cm intensity mapping. In Chapter 3, I proposed the method of using cross-correlation of galaxy survey and Lyman-α forest to understand the fluctuations of ionizing background in the intergalactic medium. Chapter 4 shows the impact of inhomogeneous reionization on 21 cm intensity mapping inference of ΛCDM model.
