The distribution of neutral hydrogen mapped by SKA-Low through the 21 cm signal provides a unique and powerful probe of the cosmic reionization process. However, this method faces significant challenges due to severe foreground contamination, which can exceed the cosmological signal by up to five orders of magnitude.
Cross-correlating 21 cm and line intensity maps such as [CII] and CO offers...
Over the past decade, large radio experiments have set ever more stringent upper limits on the 21-cm power spectrum during the Epoch of Reionization. With increased sensitivity from current and planned future surveys, we are moving fast towards detecting the 21-cm auto power spectrum. However, with the complexities of systematic effects in low-frequency instruments, validating a potential...
Helium reionization represents the most recent global transformation of the intergalactic medium, yet its main drivers and evolution remain poorly understood. Upcoming radio surveys aim to probe the Epoch of Reionization (EoR) using line-intensity mapping (LIM) techniques, with the most promising instruments being the Square Kilometre Array Phase 1 (SKA-1) MID, the Deep Synoptic Array 2000...
