Explore the theoretical foundations and observational challenges of measuring galaxy bias at high redshifts in this 16-minute conference talk. Learn how galaxy bias affects the relationship between galaxy distributions and underlying dark matter structures, with specific focus on implications for upcoming stage-5 spectroscopic surveys. Discover the methodological approaches for characterizing bias parameters in high-redshift galaxy populations and understand how these measurements will inform cosmological parameter estimation in next-generation large-scale structure surveys. Examine the theoretical predictions for galaxy bias evolution across cosmic time and the observational strategies needed to constrain these models using data from future spectroscopic missions.
