Illuminating and Tabulating the Galaxy Halo Connection

Abstract: In the near future, a new generation of massively multiplexed spectroscopic surveys, such as PFS, WAVES, and MOONS, will probe galaxies in the distant universe in vastly greater numbers than was previously possible. These data will allow us to study galaxy evolution in great detail across a wide range of cosmic times and connect galaxies to their dark matter halos. I have generated mock catalogs for each of these three planned surveys to help quantify and optimize their scientific output. These mock datasets build upon the UniverseMachine empirical model with our Calibrating Light: Illuminating Mocks By Empirical Relations (CLIMBER) procedure using UltraVISTA photometry. I will also explore the galaxy-halo connection information available using early data from the Dark Energy Spectroscopic Instrument (DESI). I have utilized information from summary statistics such as number density, the two-point correlation function, and a complementary metric known as counts-in-cylinders (CiC), which is possible thanks to the high spatial completeness of the DESI Survey Validation 3 (SV3). I will summarize my galtab algorithm, which allows this analysis to be performed with modest computational resources.
