NT30: COCM Route 3 Analysis Pipeline — Complete Execution on eROSITA-DE DR1 (All 23 FILL Fields Resolved)

Key Points

This research aims to execute the NT30 analysis pipeline on the eROSITA-DE DR1 data to resolve all FILL fields.
Utilized a 128³ grid in the analysis with a bootstrap sample of N=200.
Conducted forward modeling using ΛCDM with 25 independent realizations.
Evaluated the consistency against the NT25 pipeline with a discrepancy check.
Observed intensity I = 0.1209 ± 0.0036 with an estimated error eI = 0.1368 ± 0.0008.
The observed value lies 7.5σ above the ΛCDM baseline estimate (I_ΛCDM = 0.0916 ± 0.0039).
NT25 three-route consistency achieved with an 8.8% discrepancy, confirming pipeline integrity.

Abstract

Complete execution of the NT30 pipeline on the eROSITA-DE DR1 cosmology-optimised cluster catalogue. All 23 FILL fields resolved. I = 0. 1209 ± 0. 0036 (128³ grid, bootstrap N=200), giving eI = 0. 1368 ± 0. 0008. NT25 three-route consistency satisfied at 8. 8% discrepancy. Forward-modelled ΛCDM baseline (25 independent realisations, Eisenstein-Hu) gives I_ΛCDM = 0. 0916 ± 0. 0039; observed value lies 7. 5σ above in this pipeline. NT25 Closed. Claim 7 Advanced pending full selection-function validation and ≥100 mock realisations.
