The APOSTLE project: Local Group kinematic mass constraints and simulation candidate selection
Azadeh Fattahi, Julio F. Navarro, Till Sawala +8
We use a large sample of isolated dark matter halo pairs drawn from cosmological N-body simulations to identify candidate systems whose kinematics match that of the Local Group of…
On Arcs and Omega
Matthias Bartelmann, Andreas Huss, Joerg M. Colberg +2
The gravitational lens effect of galaxy clusters can produce large arcs from source galaxies in their background. Typical source redshifts of ~ 1 require clusters at z ~ 0.3 for ar…
Constraints on the properties of warm dark matter using the satellite galaxies of the Milky Way
Oliver Newton, Matteo Leo, Marius Cautun +5
The satellite galaxies of the Milky Way (MW) are effective probes of the underlying dark matter (DM) substructure, which is sensitive to the nature of the DM particle. In particula…
The Emperor's New Arc: gigaparsec patterns abound in a CDM universe
Till Sawala, Meri Teeriaho, Carlos S. Frenk +5
Recent discoveries of apparent large-scale features in the structure of the universe, extending over many hundreds of megaparsecs, have been claimed to contradict the large-scale i…
The halo mass function from the dark ages through the present day
Darren Reed, Richard Bower, Carlos Frenk +2
We use an array of high-resolution N-body simulations to determine the mass function of dark matter haloes at redshifts 10-30. We develop a new method for compensating for the effe…
The haloes of bright satellite galaxies in a warm dark matter universe
Mark Lovell, Vincent Eke, Carlos Frenk +7
High resolution N-body simulations of galactic cold dark matter haloes indicate that we should expect to find a few satellite galaxies around the Milky Way whose haloes have a maxi…
