英文摘要The spatial distribution of satellite galaxies encodes rich information of the structure and assembly history of galaxy clusters. In this paper, we select a red-sequence Matched-filter Probabilistic Percolation cluster sample in SDSS Stripe 82 region with 0.1 <= z <= 0.33, 20 < lambda < 100, and P-cen > 0.7. Using the high-quality weak lensing data from CS82 Survey, we constrain the mass profile of this sample. Then we compare directly the mass density profile with the satellite number density profile. We find that the total mass and number density profiles have the same shape, both well fitted by an NFW profile. The scale radii agree with each other within a 1 sigma error (r(s,gal) = 0.34(-0.03)(+0.04) Mpc versus r(s) = 0.37(-0.10)(+0.15) Mpc).
