CFHTLenS: The relation between galaxy dark matter haloes and baryons from weak gravitational lensing

Understand

We present a study of the relation between dark matter halo mass and the baryonic content of host galaxies, quantified via luminosity and stellar mass.

• Our investigation uses 154 deg2 of Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS) lensing and photometric data, obtained from the CFHT Legacy Survey.
• We employ a galaxy-galaxy lensing halo model which allows us to constrain the halo mass and the satellite fraction.
• Our analysis is limited to lenses at redshifts between 0.2 and 0.4.
