NIHAO -- XXV. Convergence in the cusp-core transformation of cold dark matter haloes at high star formation thresholds
Aaron A. Dutton, Tobias Buck, Andrea V. Macciò +3
We use cosmological hydrodynamical galaxy formation simulations from the NIHAO project to investigate the response of cold dark matter (CDM) haloes to baryonic processes. Previous…
NIHAO XXVI: Nature versus nurture, the Star Formation Main Sequence and the origin of its scatter
Marvin Blank, Liam E. Meier, Andrea V. Macciò +4
We investigate how the NIHAO galaxies match the observed star formation main sequence (SFMS) and what the origin of its scatter is. The NIHAO galaxies reproduce the SFMS and genera…
Abundance matching tested on small scales with galaxy dynamics
Andrea V. Macciò, Stephane Courteau, Nathalie N. -Q. Ouellette +1
We present a comprehensive test of the relation between stellar and total mass in galaxies as predicted by popular models based on abundance matching (AM) techniques. We use the ``…
The Dekel-Zhao profile: A mass-dependent dark-matter density profile with flexible inner slope and analytic potential, velocity dispersion, and lensing properties
Jonathan Freundlich, Fangzhou Jiang, Avishai Dekel +6
We explore a function with two shape parameters for the dark-matter halo density profile subject to baryonic effects, which is a special case of the general Zhao family of models a…
