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 dark matter to baryonic processes. The study is based on the analysis of hydrodynamicallysimulated galaxies from dwarf to Milky Way mass, drawn from the MaGICC project, whichhave been shown to match a wide range of disk scaling relationships. We find that the bestfit parameters of a generic double power-law… Expand

Cluster density slopes from dark matter-baryons energy transfer
Abstract In this paper, we extend previous works on the relation between mass and the inner slope in dark matter density profiles. We calculate that relation in the mass range going from dwarfExpand
The Tully–Fisher and mass–size relations from halo abundance matching
The Tully-Fisher relation (TFR) expresses the connection between rotating galaxies and the dark matter haloes they inhabit, and therefore contains a wealth of information about galaxy formation. WeExpand
Dark matter-baryon scaling relations from Einasto halo fits to SPARC galaxy rotation curves
Dark matter-baryon scaling relations in galaxies are important in order to constrain galaxy formation models. Here, we provide a modern quantitative assessment of those relations, by modelling theExpand

Baryon effects on the internal structure of ΛCDM haloes in the EAGLE simulations

A Baryonic Solution to the Missing Satellites Problem
It has been demonstrated that the inclusion of baryonic physics can alter the dark matter densities in the centers of low-mass galaxies, making the central dark matter slope more shallow thanExpand

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
