KiDS+GAMA: The weak lensing calibrated stellar-to-halo mass relation of
  central and satellite galaxies
  We simultaneously present constraints on the stellar-to-halo mass relation
for central and satellite galaxies through a weak lensing analysis of
spectroscopically classified galaxies. Using overlapping data from the fourth
data release of the Kilo-Degree Survey (KiDS), and the Galaxy And Mass Assembly
survey (GAMA), we find that satellite galaxies are hosted by halo masses that
are $0.53 \pm 0.39$ dex (68\% confidence, $3\sigma$ detection) smaller than
those 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 formation
models, whereby infalling satellite galaxies are preferentially stripped of
their dark matter. We find consistent results with similar uncertainties when
comparing constraints from a standard azimuthally averaged galaxy-galaxy
lensing analysis and a two-dimensional likelihood analysis of the full shear
field. As the latter approach is somewhat biased due to the lens incompleteness
and as it does not provide any improvement to the precision when applied to
actual data, we conclude that stacked tangential shear measurements are
best-suited for studies of the galaxy-halo connection.
