The DESI One-Percent survey: constructing galaxy-halo connections for ELGs and LRGs using auto and cross correlations

Understand

In the current Dark Energy Spectroscopic Instrument (DESI) survey, emission line galaxies (ELGs) and luminous red galaxies (LRGs) are essential for mapping the dark matter distribution at $z \sim 1$.

• We measure the auto and cross correlation functions of ELGs and LRGs at $0.8<z\leq 1.0$ from the DESI One-Percent survey.
• Following Gao et al.
• (2022), we construct the galaxy-halo connections for ELGs and LRGs simultaneously.
