Dependence of galaxy clustering on UV-luminosity and stellar mass at $z
  \sim 4 - 7$
  We investigate the dependence of galaxy clustering at $z \sim 4 - 7$ on
UV-luminosity and stellar mass. Our sample consists of $\sim$ 10,000
Lyman-break galaxies (LBGs) in the XDF and CANDELS fields. As part of our
analysis, the $M_\star - M_{\rm UV}$ relation is estimated for the sample,
which is found to have a nearly linear slope of $d\log_{10} M_\star / d M_{\rm
UV} \sim 0.44$. We subsequently measure the angular correlation function and
bias in different stellar mass and luminosity bins. We focus on comparing the
clustering dependence on these two properties. While UV-luminosity is only
related to recent starbursts of a galaxy, stellar mass reflects the integrated
build-up of the whole star formation history, which should make it more tightly
correlated with halo mass. Hence, the clustering segregation with stellar mass
is expected to be larger than with luminosity. However, our measurements
suggest that the segregation with luminosity is larger with $\simeq 90\%$
confidence (neglecting contributions from systematic errors). We compare this
unexpected result with predictions from the \textsc{Meraxes} semi-analytic
galaxy formation model. Interestingly, the model reproduces the observed
angular correlation functions, and also suggests stronger clustering
segregation with luminosity. The comparison between our observations and the
model provides evidence of multiple halo occupation in the small scale
clustering.
