Cynthia Chiang (hosted by Nagy/Errando), of McGill University, will present this talk.
Redshifted 21-cm emission from neutral hydrogen is a powerful tool for observational cosmology research. Measurements across a wide range of radio frequencies allow us to access redshifts that encompass a vast comoving volume, spanning both cosmic dawn and the formation of large-scale structure. Chiang will describe the HIRAX, PRIZM, and ALBATROS experiments, which aim to shed new light on the universe's evolution via redshifted 21-cm measurements.
