Description

The distribution of dark matter (DM) halos is crucial in understanding the large-scale structure of the universe and galaxy evolution and the various factors that affect it. Accreting Super Massive Black Holes, or Active Galactic Nuclei (AGN), may have an important role to play in the galaxy-halo connection. Studying AGN in dense environments, particularly the fraction of satellites and centrals containing an AGN as a function of mass and redshift provides hints to the key questions, what halos do AGN live in and how are they triggered?
In this work we use the halo-based group finder to investigate the multi-tracer AGN-galaxy-halo central and satellite fractions in the Dark Energy Spectroscopic Instrument (DESI) survey. The results obtained from the above methods will be validated using the Uchuu simulations to investigate the galaxy bias at small scales.
