We constrain the HOD of each sample and test possible HOD extensions by fitting the redshift-space galaxy 2-point correlation functions in (equation presented) Mpc in a set of fiducial redshift bins. We use ABACUSSUMMIT cubic boxes at Planck 2018 cosmology as model templates and forward model galaxy clustering with the ABACUSHOD package. We achieve good fits with a standard HOD model with velocity bias, and we find no evidence for galaxy assembly bias or satellite profile modulation at the current level of statistical uncertainty. For LRGs in (equation presented), we infer a satellite fraction of (equation presented) per cent, a mean halo mass of log10 (equation presented), and a linear bias of (equation presented). For LRGs in (equation presented), we find (equation presented) per cent, (equation presented). For QSOs, we infer (equation presented) per cent, (equation presented) in redshift range (equation presented). Using these fits, we generate a large suite of high fidelity galaxy mocks, forming the basis of systematic tests for DESI Y1 cosmological analyses. We also study the redshift-evolution of the DESI LRG sample from z = 0.4 up to z = 1.1, revealling significant and interesting trends in mean halo mass, linear bias, and satellite fractionThis material is based upon work supported by the U.S. Department of Energy (DOE), Office of Science, Office of High-Energy Physics, under Contract No. DE-AC02-05CH11231, and by the National Energy Research Scientific Computing Center, a DOE Office of Science User Facility under the same contract.
