Abstract
Lyman-alpha galaxies offer a way to map structure beyond redshift two and connect galaxy surveys with microwave-background lensing. This talk demonstrates selection from IBIS medium-band images and spectroscopic follow-up with DESI. Joint clustering measurements of these galaxies and quasars constrain bias, small-scale velocity effects and radiative-transfer contributions, testing the modelling needed for future high-redshift surveys.
