   "description": "This cluster of papers represents advancements in radio astronomy techniques and instruments, with a focus on observing the epoch of reionization, cosmic dawn, and the 21 cm signal from neutral hydrogen. It includes research on low-frequency telescopes, interferometric imaging, foreground subtraction methods, and the challenges of mitigating radio frequency interference. The Square Kilometre Array (SKA) precursor projects and wide-field surveys are also prominent in this cluster.",
