The median density of the Universe
Jens Stücker, Philipp Busch, Simon D. M. White
Despite the fact that the mean matter density of the universe has been measured to an accuracy of a few percent within the standard CDM paradigm, its median density is not known…
Modelling the line-of-sight contribution in substructure lensing
Giulia Despali, Simona Vegetti, Simon D. M. White +2
We investigate how Einstein rings and magnified arcs are affected by small-mass dark-matter haloes placed along the line-of-sight to gravitational lens systems. By comparing the gr…
EMERGE - An empirical model for the formation of galaxies since
Benjamin P. Moster, Thorsten Naab, Simon D. M. White
We present EMERGE, an Empirical ModEl for the foRmation of GalaxiEs, describing the evolution of individual galaxies in large volumes from to the present day. We assign a…
Lessons from the Auriga discs: The hunt for the Milky Way's ex-situ disc is not yet over
Facundo A. Gómez, Robert J. J. Grand, Antonela Monachesi +7
We characterize the contribution from accreted material to the galactic discs of the Auriga Project, a set of high resolution magnetohydrodynamic cosmological simulations of late-t…
The Hydrangea simulations: galaxy formation in and around massive clusters
Yannick M. Bahé, David J. Barnes, Claudio Dalla Vecchia +12
We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in simulations of massive galaxy clusters (M_200c = 10^14-10^15 M_Sun) with baryon particle mas…
The Cluster-EAGLE project: global properties of simulated clusters with resolved galaxies
David J. Barnes, Scott T. Kay, Yannick M. Bahe +10
We introduce the Cluster-EAGLE (C-EAGLE) simulation project, a set of cosmological hydrodynamical zoom simulations of the formation of galaxy clusters in the mass range $10^{1…
