Photometric Objects Around Cosmic Webs (PAC) Delineated in a Spectroscopic survey. II. Morphology, Color and Size Dependences of the Stellar-halo Mass Relation for Massive Galaxies

Abstract

In this paper, we report a robust measurement of the morphology, color and galaxy size dependences of the stellar-halo mass relation (SHMR) at the high mass end ($10^{11.3}{\mathrm{M}}_{\odot }<M_{\star }<10^{11.7}{\mathrm{M}}_{\odot }$) at redshift $z_s\sim 0.6$ (Throughout the paper, we use $z_s$ for redshift, $z$ for the z-band magnitude.). Applying our method, Photometric objects Around Cosmic webs (PAC), developed in a previous work to CMASS and HSC-SSP observations, we measure the excess surface density (${\bar{n}}_2{w}_p(r_p)$) of satellites around massive central galaxies with different morphologies indicated by Sérsic index $n$. We find that more compact (larger $n$) central galaxies are surrounded by more satellites. With the abundance matching method, we estimate halo mass for the central galaxies, and find that halo mass is increased monotonically with $n$, solid evidence for a morphology dependence of SHMR. Specifically, our results show that the most compact galaxies ($n>6$) have the halo mass around 5.5 times larger than the disk galaxies ($n<2$). Similarly, using the effective radius $R_e$ and the rest-frame $u-r$ color, we find that red (large) galaxies reside in halos that are in average $2.6$ ($2.3$) times more massive than those hosting blue (small) galaxies.
