We measure the evolution in the virial mass-to-light ratio(M_200/L_B) and virial-to-stellar mass ratio (M_200/M*) for isolated ~;L*galaxies between z~;1 and z~;0 by combining data from the DEEP2 GalaxyRedshift Survey and the Sloan Digital Sky Survey. Utilizing the motionsof satellite galaxies around isolated galaxies, we measure line-of-sightvelocity dispersions and derive dark matter halo virial masses for thesehost galaxies. At both epochs the velocity dispersionof satellitescorrelates with…

NEW CONSTRAINTS ON THE EVOLUTION OF THE STELLAR-TO-DARK MATTER CONNECTION: A COMBINED ANALYSIS OF GALAXY-GALAXY LENSING, CLUSTERING, AND STELLAR MASS FUNCTIONS FROM z = 0.2 to z = 1*
Using data from the COSMOS survey, we perform the first joint analysis of galaxy-galaxy weak lensing, galaxy spatial clustering, and galaxy number densities. Carefully accounting for sample variance
Optical-to-virial velocity ratios of local disc galaxies from combined kinematics and galaxy–galaxy lensing
In this paper, we measure the optical-to-virial velocity ratios V_(opt)/V_(200c) of disc galaxies in the Sloan Digital Sky Survey (SDSS) at a mean redshift of 〈z〉 = 0.07 and with stellar masses 10^9
Connecting stellar mass and star-formation rate to dark matter halo mass out to z ∼ 2
We have constructed an extended halo model (EHM) which relates the total stellar mass and star-formation rate (SFR) to halo mass (M_h). An empirical relation between the distribution functions of

We present new determinations of the stellar-to-halo mass relation (SHMR) at $z=0-10$ that match the evolution of the galaxy stellar mass function, the SFR$-M_*$ relation,and the cosmic star
The Halo Masses of Galaxies to z ∼ 3: A Hybrid Observational and Theoretical Approach
We use a hybrid observational/theoretical approach to study the relation between galaxy kinematics and the derived stellar and halo masses of galaxies up to z=3 as a function of stellar mass,
The stellar-to-halo mass relations of local galaxies segregates by color
We derive the stellar-to-halo mass relations, SHMR, of local blue and red central galaxies separately, as well as the fraction of halos hosting blue/red central galaxies. We find that: 1) the SHMR of
Where stars form and live at high redshift: clues from the infrared
The relation between dark matter halos and the loci of star formation at high redshift is a pressing question in contemporary cosmology. Matching the abundance of halos to the abundance of infrared
