The stellar-to-halo mass relation of central galaxies across three orders of halo mass
Victoria Toptun, Paola Popesso, Ilaria Marini +9
The stellar content of galaxies is tightly connected to the mass and growth of their host dark matter halos. Observational constraints on this relation remain limited, particularly…
Trinity VII. Predictions for the Observable Correlation Functions of Accreting Black Holes
Oddisey Knox, Haowen Zhang, Peter Behroozi
The quasar correlation function assesses the occurrence of quasar pairs as a function of separation, which is strongly influenced by quasar host halo masses. The empirical Trinity…
The SAGA Survey. V. Modeling Satellite Systems around Milky Way-mass Galaxies with Updated UniverseMachine
Yunchong Wang, Ethan O. Nadler, Yao-Yuan Mao +11
Environment plays a critical role in shaping the assembly of low-mass galaxies. Here, we use the UniverseMachine (UM) galaxy-halo connection framework and the Data Release 3 of the…
ChemicalUniverseMachine I: Uncovering the Cosmic Evolution of Metals in the Galaxy-ISM-CGM Ecosystem
Moka Nishigaki, Peter Behroozi, Masami Ouchi +5
We present an empirical chemical evolution model that explains the distribution of metals in the interstellar medium (ISM) and the circumgalactic medium (CGM) of galaxies based on…
Star-forming and Quiescent Central Galaxies Cluster Similarly: Implications for the Galaxy-Halo Connection
James Kakos, Aldo Rodriguez-Puebla, Joel R. Primack +4
We measure the clustering of low-redshift SDSS galaxies as a function of stellar mass () and specific star formation rate (sSFR) and compare the result…
Measuring the conditional luminosity and stellar mass functions of galaxies by combining the DESI LS DR9, SV3 and Y1 data
Yirong Wang, Xiaohu Yang, Yizhou Gu +42
In this investigation, we leverage the combination of Dark Energy Spectroscopic Instrument Legacy imaging Surveys Data Release 9 (DESI LS DR9), Survey Validation 3 (SV3), and Year…
