| Abstract: | Observations of 21-cm radiation provide the ultimate tool for precision cosmology. I'll describe the 21-cm signal and the planned experiments to measure its fluctuations and show how techniques originally developed for CMB weak-lensing reconstruction can be applied to study the properties of different cosmic structures (from mundane galaxy clusters to more exotic defects), focusing on the tradeoffs between the different experimental parameters. |
