We simultaneously present constraints on the stellar-to-halo mass relationfor central and satellite galaxies through a weak lensing analysis ofspectroscopically classified galaxies. Using overlapping data from the fourthdata release of the Kilo-Degree Survey (KiDS), and the Galaxy And Mass Assemblysurvey (GAMA), we find that satellite galaxies are hosted by halo masses thatare $0.53 \pm 0.39$ dex (68\% confidence, $3\sigma$ detection) smaller thanthose of central galaxies of the same stellar mass (for a stellar mass of$\log(M_{\star}/M_{\odot}) = 10.6$). This is consistent with galaxy formationmodels, whereby infalling satellite galaxies are preferentially stripped oftheir dark matter. We find consistent results with similar uncertainties whencomparing constraints from a standard azimuthally averaged galaxy-galaxylensing analysis and a two-dimensional likelihood analysis of the full shearfield. As the latter approach is somewhat biased due to the lens incompletenessand as it does not provide any improvement to the precision when applied toactual data, we conclude that stacked tangential shear measurements arebest-suited for studies of the galaxy-halo connection.
