Assessing the large-scale angular clustering of UNIONS Lyman Break Galaxies via cross-correlations
The episode reviews the paper 'Assessing the large-scale angular clustering of UNIONS Lyman Break Galaxies via Cross-Correlations.' The hosts discuss how image artifacts make direct auto-clustering unreliable. They detail a shift to using cross-correlation with external data (like Planck CMB lensing). The findings confirm this signal is robust and consistent with theory, providing a reliable method for future cosmological studies.
