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…
One Galaxy Sample to Rule Them All: Halo Occupation Distribution Modeling of DES Year 3 Source Galaxies
Andrés N. Salcedo, Tim Eifler, Peter Behroozi
For the joint analysis of second-order weak lensing and galaxy clustering statistics, so-called analyses, the selection and characterization of optimal galaxy samples…
Using Cumulative Number Densities to Compare Galaxies across Cosmic Time
Peter Behroozi, Danilo Marchesini, Risa Wechsler +3
Comparing galaxies across redshifts at fixed cumulative number density is a popular way to estimate the evolution of specific galaxy populations. This method ignores scatter in mas…
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…
