Constraints on the relationship between stellar mass and halo mass at low and high redshift
We use a statistical approach to determine the relationship between the stellar masses of galaxies and the masses of the dark matter halos in which they reside. We obtain a parameterizedExpand
Cold dark matter haloes in the Planck era: evolution of structural parameters for Einasto and NFW profiles
We present the evolution of the structure of relaxed cold dark matter haloes in the cosmology from the Planck satellite. Our simulations cover 5 decades in halo mass, from dwarf galaxies to galaxyExpand
Concentration, spin and shape of dark matter haloes as a function of the cosmological model: WMAP1, WMAP3 and WMAP5 results
We investigate the effects of changes in the cosmological parameters between the Wilkinson Microwave Anisotropy Probe (WMAP) 1st, 3rd and 5th year results on the structure of dark matter haloes. WeExpand
Concentration, spin and shape of dark matter haloes: Scatter and the dependence on mass and environment
We use a series of cosmological N-body simulations for a flat A cold dark matter (ACDM) cosmology to investigate the structural properties of dark matter haloes, at redshift zero, in the mass range 3Expand
Non-linear evolution of cosmological structures in warm dark matter models
The dark energy dominated warm dark matter (WDM) model is a promising alternative cosmological scenario. We explore large-scale structure formation in this paradigm. We do this in two different ways:Expand
The dependence of dark matter profiles on the stellar-to-halo mass ratio: a prediction for cusps versus cores
We use a suite of 31 simulated galaxies drawn from the MaGICC project to investigate the effects of baryonic feedback on the density profiles of dark matter haloes. The sample covers a wide massExpand
A mass-dependent density profile for dark matter haloes including the influence of galaxy formation
ABSTRACT We introduce a mass dependent density profile to describe the distribution of dark matterwithin galaxies, which takes into account the stellar-to-halo mass dependence of the responseof darkExpand
We revisit the well known discrepancy between the observed number of Milky Way (MW) dwarf satellite companions and the predicted population of cold dark matter (CDM) subhalos, in light of the dozenExpand
NIHAO - XI. Formation of ultra-diffuse galaxies by outflows
We address the origin of Ultra-Diffuse Galaxies (UDGs), which have stellar masses typical of dwarf galaxies but effective radii of Milky Way-sized objects. Their formation mechanism, and whether theyExpand
Making Galaxies in a Cosmological Context: The Need for Early Stellar Feedback
We introduce the Making Galaxies in a Cosmological Context (MaGICC) program of smoothed particle hydrodynamics (SPH) simulations. We describe a parameter study of galaxy formation simulations of anExpand
