We demonstrate that the feedback from stellar bulges can, in principle, play an essential role in shaping the halo gas of galaxies with substantial bulge components by conducting 1D hydrodynamical sim...

We investigate the physical mechanisms of tidal heating and satellite disruption in cold dark matter host haloes using N-body simulations based on cosmological initial conditions. We show the importan...

We present a detailed investigation of the changing relationship between galaxies and the dark matter haloes they inhabit from z ~ 1.2 to the present day. We do this by comparing precise galaxy cluste...

The metallicity structure of galactic haloes is one of the major
unknowns in modern galactic astrophysics and observational cosmology. Hereby we
outline a very simple method for obtaining at least a...

Simulated dark matter haloes are tted by self-similar, universal
density pro les, where the scaled parameters depend only on a scaled (truncation)
radius, = R=r0, which, in turn, is supposed to b...
