QCB Void vs. Filament Test - Pre-Registration Amendment v2 (Version 3: Catalog Correction)

Key Points

The aim is to test if galaxies exhibit different gravitational behavior in filament galaxies compared to void galaxies while controlling for baryonic properties.
Amended catalog citations for voids and filaments
Specified prediction, methodology, and decision criteria for testing
Pre-registered analysis before data access
Identified appropriate void catalogs for the SPARC redshift range
Documented exploratory density proxy results
Outlined confirmatory test pathways

Abstract

VERSION 3 (April 2, 2026): Amendment v2 (DEV-001) - Corrects catalog citation error identified in Version 2. Specifies appropriate void catalogs (Courtois et al. 2023, A&A 673, A38) compatible with SPARC redshift range. Documents exploratory density proxy result and confirmatory test pathway.s Pre-registration of the QCB void vs. filament environment test, deposited before any data access. Specifies exact prediction, methodology, and decision criteria for testing whether galaxies show different gravitational behavior in filament galaxies vs. void galaxies after controlling for baryonic properties. This document establishes a public timestamp before analysis begins.
