Photometric Objects around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. I. Methods

Understand

We provide a method for estimating the projected density distribution $\bar{n}_2w_p(r_p)$ of photometric objects around spectroscopic objects in a redshift survey.

• This quantity describes the distribution of Photometric sources with certain physical properties (e.g.
• luminosity, mass, color etc) Around Cosmic webs (PAC) traced by the spectroscopic objects.
• The method can make full use of current and future deep and wide photometric surveys to explore the formation of galaxies up to medium redshift ($z_s < 2$), with the aid of cosmological redshift surveys that sample only a fairly limited species of objects (e.g.
