Galaxy-Galaxy Weak-lensing Measurements from SDSS. II. Host Halo Properties of Galaxy Groups

In this second paper in a series studying galaxy-galaxy lensing signals using Sloan Digital Sky Survey Data Release 7 (SDSS DR7), we present our measurement and modeling of the lensing signals around groups of galaxies. We divide the groups into four halo mass bins and measure the signals around fou...
