DESI Cosmic Void Galaxies
The first Analysis-Ready Dataset for astronomy — environmental quenching research as the proving ground
This repository builds an enriched, analysis-ready dataset from DESI Data Release 1, combining galaxy catalogs, void classifications, QSO properties, and spectral data into a unified resource. The environmental quenching study serves as the first consumer application and validation of the ARD architecture.

Research Question
By comparing void galaxies (isolated) to wall galaxies (in denser environments), we disentangle "nature" from "nurture" in galaxy evolution. Recent DESI DR1 work shows void galaxies tend to be fainter, less massive, and more star-forming.
