Universal structure of dark matter haloes over a mass range of 20 orders of magnitude
Jie Wang, Sownak Bose, Carlos S. Frenk +4
Cosmological models in which dark matter consists of cold elementary particles predict that the dark halo population should extend to masses many orders of magnitude below those at…
Chemodynamics of barred galaxies in cosmological simulations: On the Milky Way's quiescent merger history and in-situ bulge
F. Fragkoudi, R. J. J. Grand, R. Pakmor +9
We explore the chemodynamical properties of a sample of barred galaxies in the Auriga magneto-hydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) bulges,…
Empirical constraints on the formation of early-type galaxies
Benjamin P. Moster, Thorsten Naab, Simon D. M. White
We present constraints on the formation and evolution of early-type galaxies (ETGs) with the empirical model EMERGE. The parameters of this model are adjusted so that it reproduces…
Gas accretion and galactic fountain flows in the Auriga cosmological simulations: angular momentum and metal re-distribution
Robert J. J. Grand, Freeke van de Voort, Jolanta Zjupa +7
Using a set of 15 high-resolution magnetohydrodynamic cosmological simulations of Milky Way formation, we investigate the origin of the baryonic material found in stars at redshift…
The Tessellation-Level-Tree: characterising the nested hierarchy of density peaks and their spatial distribution in cosmological N-body simulations
Philipp Busch, Simon D. M. White
We use the Millennium and Millennium-II simulations to illustrate the Tessellation-Level-Tree (TLT), a hierarchical tree structure linking density peaks in a field constructed by v…
The globular cluster system of the Auriga simulations
Timo L. R. Halbesma, Robert J. J. Grand, Facundo A. Gómez +5
We investigate whether the galaxy and star formation model used for the Auriga simulations can produce a realistic globular cluster (GC) population. We compare statistics of GC can…
