Description

The Photometric objects Around Cosmic webs (PAC) approach developed in \cite{2022ApJ...925...31X} has the advantage of making full use of the spectroscopic and deeper photometric surveys. With the merits of PAC, we can accurately measure quasars-galaxy cross-correlations at small scale down to $0.1\,h^{-1}{\rm{Mpc}}$ and at different stellar mass bins. We calculate the excess surface density $\bar{n}_2w_{{\rm{p}}}$ of photometric objects around quasars down to stellar mass $10^{10.80}\,M_{\odot}$ at redshift $0.8
