Halo mass and assembly history exposed in the faint outskirts: the stellar and dark matter haloes of Illustris galaxies
We use the Illustris simulations to gain insight into the build-up of the outer, low-surface brightness regions which surround galaxies. We characterize the stellar haloes by means of the logarithmic slope of the spherically averaged stellar density profiles, α[subscript STARS] at z = 0, and we rela...
