Top panel: Two-point correlation function derived using the LS estimator for the cross-correlation between quasar pairs and individual quasars within the redshift interval 2.2 ≤ z ≤ 2.5. The 2PCF for the entire subsample is included, computed using the resampling bootstrap method, as well as the 2PCF for isolated quasars not belonging to any pair. Bottom panel: The same 2PCFs are presented on a logarithmic scale.
