The FENIKS Survey: Stellar-Halo Mass Relationship of Central and Satellite Galaxies in UDS and COSMOS at 0.2 < z < 4.5
The FENIKS Survey analyzed the Stellar-to-Halo mass relationship (SHMR) from z=0.2 to 4.5 using galaxy clustering and abundance data from COSMOS and UDS catalogs. A novel 'smooth-z' fitting method was used to connect measurements across redshift bins, revealing a clear downsizing trend where peak star formation efficiency decreases as halo mass increases, indicating that more massive halos assemble their stellar mass earlier.
