Improving Photometric Galaxy Clustering Constraints With Cross-Bin Correlations
Jordan Krywonos, Jessica Muir, Matthew C. Johnson
Clustering studies in current photometric galaxy surveys focus solely on auto-correlations, neglecting cross-correlations between redshift bins. We evaluate the potential advantage…
