Abstract:
We present clustering analysis results from 10381 Lyman break galaxies
(LBGs) at z∼4-7, identified in the Hubble legacy deep imaging and new
complimentary large-area Subaru/Hyper Suprime-Cam data. We measure the
angular correlation functions of these LBGs at z∼4, 5, 6, and 7 and
fit these measurements using halo occupation distribution (HOD) models
that provide an estimate of halo masses, Mh~(1-20)x1011M☉.
Our Mh estimates agree with those obtained by previous clustering
studies in a UV-magnitude versus Mh plane and allow us to calculate
stellar-to-halo mass ratios (SHMRs) of LBGs. By comparison with the
z∼0 SHMR, we identify evolution of the SHMR from z∼0 to z∼4 and from
z∼4 to z∼7 at the >98% confidence levels. The SHMR decreases by a
factor of ∼2 from z∼0 to 4 and increases by a factor of ∼4 from z∼4 to
7 at the dark matter halo mass of Mh∼1011M_☉. We compare our
SHMRs with results of a hydrodynamic simulation and a semianalytic
model and find that these theoretical studies do not predict the SHMR
increase from z∼4 to 7. We obtain the baryon conversion efficiency
(BCE) of LBGs at z∼4 and find that the BCE increases with increasing
dark matter halo mass. Finally, we compare our clustering+HOD
estimates with results from abundance matching techniques and conclude
that the Mh estimates of the clustering+HOD analyses agree with those
of the simple abundance matching within a factor of 3, and that the
agreement improves when using more sophisticated abundance matching
techniques that include subhalos, incompleteness, and/or evolution in
the star formation and stellar mass functions.
Description:
We use 10 deep optical-near-IR imaging data sets of the Hubble Ultra
Deep Field (HUDF), Great Observatories Origins Deep Survey
(GOODS)-North-Deep, GOODS-North-Wide, GOODS-South-Deep,
GOODS-South-Wide, Cosmic Assembly Near-infrared Deep Extragalactic
Legacy Survey (CANDELS)-All-Wavelength Extended Groth Strip
International Survey (AEGIS), CANDELS-Cosmological Evolution Survey
(COSMOS), CANDELS-Ultra Deep Survey (UDS), Hubble Frontier Field
(HFF)-Abell2744P, and HFF-MACS0416P that are taken with ACS and WFC3
on the HST. The total area of the Hubble data is ∼600arcmin2. The
typical FWHMs of the PSFs of ACS and WFC3 images are 0.1" and 0.2",
respectively.
