Cosmological HI Intensity Mapping with HIRAX

Explore the cutting-edge field of cosmological HI intensity mapping in this 23-minute conference talk by Alexandre Refregier. Learn about the Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) and its role in advancing our understanding of large-scale cosmic structures. Gain insights into how HIRAX contributes to the ongoing efforts in precision cosmology, complementing other major surveys like SDSS, DES, and upcoming projects such as DESI and SKA. Discover the potential of HI intensity mapping in probing the Universe at different redshifts and its significance in the context of multi-messenger cosmology. This talk is part of the "Largest Cosmological Surveys and Big Data Science" program organized by the International Centre for Theoretical Sciences, aimed at exposing researchers to frontier cosmology research and developing skills for analyzing large survey data.
