Population-Level Constraints on Far-Infrared Excess in Nearby Galaxies: A 250 𝜇m Control-Band Anchored Test Using GAMA DR4
Abstract
This preprint presents a population-level control-band infrared test anchored at 250 μm using GAMA DR4 data. Applying matched-null stratified refinement, it evaluates whether apparent far-infrared excess persists under progressive covariate conditioning. As a control-band analysis, it tests whether excess behavior observed at longer wavelengths reflects structural effects or methodological artifacts.
