The DESI One-Percent Survey: A concise model for galactic conformity of ELGs

Understand

Galactic conformity is the phenomenon in which a galaxy of a certain physical property is correlated with its neighbors of the same property, implying a possible causal relationship.

• The observed auto correlations of emission line galaxies (ELGs) from the highly complete DESI One-Percent survey exhibit a strong clustering signal on small scales, providing clear evidence for the conformity effect of ELGs.
• Building upon the original subhalo abundance matching (SHAM) method developed by Gao et al.
• (2022, 2023), we propose a concise conformity model to improve the ELG-halo connection.
