“…Our results indicate, however, that the modelling of red/blue-split galaxy alignments may be insufficient to describe samples with variable central/satellite galaxy fractions.…”

CFHTLenS: The Environmental Dependence of Galaxy Halo Masses from Weak Lensing by Gillis, B, Hudson, M, Erben, T, Heymans, C, Hildebrandt, H, Hoekstra, H, Kitching, T, Mellier, Y, Miller, L, Waerbeke, L, Bonnett, C, Coupon, J, Fu, L, Hilbert, S, Rowe, B, Schrabback, T, Semboloni, E, Uitert, E, Velander, M

“…We use weak gravitational lensing to analyse the dark matter halos around satellite galaxies in galaxy groups in the CFHTLenS dataset. …”

The dependence of intrinsic alignment of galaxies on wavelength using KiDS and GAMA by Georgiou, C, Johnston, H, Hoekstra, H, Viola, M, Kuijken, K, Joachimi, B, Chisari, N, Farrow, D, Hildebrandt, H, Holwerda, B, Kannawadi, A

“…Separating the sample into central/satellite and red/blue galaxies, we find that the difference is dominated by red satellite galaxies.…”

GAMA+KiDS: Alignment of galaxies in galaxy groups and its dependence on galaxy scale by Georgiou, C, Chisari, N, Fortuna, M, Hoekstra, H, Kuijken, K, Joachimi, B, Vakili, M, Bilicki, M, Dvornik, A, Erben, T, Giblin, B, Heymans, C, Napolitano, N, Shan, H

“…In this work, we measure the alignment of shapes of satellite galaxies, in galaxy groups, with respect to the brightest group galaxy (BGG), as well as alignments of the BGG shape with the satellite positions, using the highly complete Galaxy And Mass Assembly (GAMA) spectroscopic survey and deep imaging from the Kilo Degree Survey. …”

The stellar-to-halo mass relation of GAMA galaxies from 100 deg 2 of KiDS weak lensing data by van Uitert, E, Cacciato, M, Hoekstra, H, Brouwer, M, Sifón, C, Viola, M, Baldry, I, Bland-Hawthorn, J, Brough, S, Brown, M, Choi, A, Driver, S, Erben, T, Heymans, C, Hildebrandt, H, Joachimi, B, Kuijken, K, Liske, J, Loveday, J, McFarland, J, Miller, L, Nakajima, R, Peacock, J, Radovich, M, Robotham, A, Schneider, P, Sikkema, G, Taylor, E, Verdoes Kleijn, G

“…Furthermore, we find that the stellar-to-halo mass relation of central galaxies can also be obtained by modelling the lensing signal and stellar mass function of satellite galaxies only, which shows that the assumptions to model the satellite contribution in the halo model do not significantly bias the stellar-to-halo mass relation. …”
