Abstract
We investigate the dependence of galaxy clustering at z ~ 4-7 on UV luminosity and stellar mass. Our sample consists of ~10 000 Lyman-break galaxies in the eXtreme Deep Field (XDF) and Cosmic Assembly Near-infrared Deep Extragalatic Legacy Survey (CANDELS) fields. As part of our analysis, the M*-MUV relation is estimated for the sample, which is found to have a nearly linear slope of dlog10M*/dMUV ~ 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 integrate..
