We use a statistical approach to determine the relationship between the stellar masses of galaxies and the masses of the dark matter halos in which they reside. We obtain a parameterized stellar-to-halo mass (SHM) relation by populating halos and subhalos in an N-body simulation with galaxies and requiring that the observed stellar mass function be reproduced. We find good agreement w ith constraints from galaxy-galaxy lensing and predictions of semi-analytic models. Using this mapping, and the… Expand
The evolution of the stellar mass versus halo mass relationship
We present an analysis of the predictions made by the GALFORM semi-analytic galaxy formation model for the evolution of the relationship between stellar mass and halo mass. We show that for theExpand
On the scatter in the relation between stellar mass and halo mass: random or halo formation time dependent?
The empirical HOD model of Wang et al. 2006 fits, by construction, both the stellar mass function and correlation function of galaxies in the local Universe. In contrast, the semi-analytical modelsExpand
The stellar-to-halo mass relation over the past 12 Gyr
Understanding how galaxy properties are linked to the dark matter halos they reside in, and how they co-evolve is a powerful tool to constrain the processes related to galaxy formation. TheExpand
A Comprehensive Analysis of Uncertainties Affecting the Stellar Mass - Halo Mass Relation for 0
We conduct a comprehensive analysis of the relationship between central galaxies and their host dark matter halos, as characterized by the stellar mass-halo mass (SM-HM) relation, with rigorousExpand
The dwarfs beyond: The stellar-to-halo mass relation for a new sample of intermediate redshift low-mass galaxies
A number of recent challenges to the standard ΛCDM paradigm relate to discrepancies that arise in comparing the abundance and kinematics of local dwarf galaxies with the predictions of numericalExpand
Galaxy stellar mass assembly: the difficulty matching observations and semi-analytical predictions
Semi-analytical models (SAMs) are currently the best way to understand the formation of galaxies within the cosmic dark-matter structures. While they fairly well reproduce the local stellar massExpand
The Impact of Environment on the Stellar Mass - Halo Mass Relation.
A large variance exists in the amplitude of the Stellar Mass - Halo Mass (SMHM) relation for group and cluster-size halos. Using a sample of 254 clusters, we show that the magnitude gap between theExpand
The stellar mass function and efficiency of galaxy formation with a varying initial mass function
Several recent observational studies have concluded that the initial mass function (IMF) of stars varies systematically with galaxy properties such as velocity dispersion. In this paper, weExpand
We contend that a single power-law halo mass distribution is appropriate for direct matching to the stellar masses of observed Local Group dwarf galaxies, allowing the determination of the slope ofExpand
Linking haloes to galaxies: how many halo properties are needed?
Recent studies emphasize that an empirical relation between the stellar mass of galaxies and the mass of their host dark matter subhaloes can predict the clustering of galaxies and its evolution withExpand


Constraining galaxy formation and cosmology with the conditional luminosity function of galaxies
We use the conditional luminosity function �(L|M)dL, which gives the number of galaxies with luminosities in the range L±dL/2 that reside in a halo of mass M, to link the distribution of galaxies toExpand
Modeling galaxy - mass correlations in dissipationless simulations
We use high-resolution, dissipationless simulations of the concordance flat ?CDM model to make predictions for the galaxy-mass correlations and compare them with the recent Sloan Digital Sky SurveyExpand
The Halo Occupation Distribution: Toward an Empirical Determination of the Relation between Galaxies and Mass
We investigate galaxy bias in the framework of the halo occupation distribution (HOD), which defines the bias of a population of galaxies by the conditional probability P(N|M) that a dark matter haloExpand
Modelling galaxy clustering in a high-resolution simulation of structure formation
We use the Millennium Simulation, a 10 billion particle simulation of the growth of cosmic structure, to construct a new model of galaxy clustering. We adopt a methodology that falls midway betweenExpand
The impact of Spitzer infrared data on stellar mass estimates – and a revised galaxy stellar mass function at 0 < z < 5
Aims. We estimate stellar masses of galaxies in the high redshift universe with the intention of determining the influence of newly available Spitzer/IRAC infrared data on the analysis. Based on theExpand

Analytic model for galaxy and dark matter clustering
We investigate an analytic model to compute the non-linear power spectrum of dark matter, galaxies and their cross-correlation. The model is based on Press–Schechter haloes, which cluster and haveExpand
Stellar mass-to-light ratios and the Tully-Fisher relation
We have used a suite of simplified spectrophotometric spiral galaxy evolution models to argue that there are substantial variations in stellar mass-to-light (M/L) ratios within and among galaxies,Expand
Theoretical Models of the Halo Occupation Distribution: Separating Central and Satellite Galaxies
The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers ofExpand
