Fossil remnants of reionization in the halo of the Milky Way
P. Madau, M. Kuhlen, J. Diemand +4
Our recently completed one billion particle Via Lactea II simulation of a Milky Way-sized dark matter halo resolves over 50,000 gravitationally bound clumps orbiting today within t…
Clumps and streams in the local dark matter distribution
J. Diemand, M. Kuhlen, P. Madau +4
In cold dark matter cosmological models, structures form and grow by merging of smaller units. Numerical simulations have shown that such merging is incomplete; the inner cores of…
Virial Scaling of Massive Dark Matter Halos: Why Clusters Prefer a High Normalization Cosmology
A. E. Evrard, J. Bialek, M. Busha +14
We present a precise estimate of the bulk virial scaling relation of halos formed via hierarchical clustering in an ensemble of simulated cold dark matter cosmologies. The result i…
Velocity distributions in clusters of galaxies
A. Faltenbacher, J. Diemand
We employ a high-resolution dissipationless N-body simulation of a galaxy cluster to investigate the impact of subhalo selection on the resulting velocity distributions. Applying a…
Cusps in CDM halos
Juerg Diemand, Marcel Zemp, Ben Moore +2
We resolve the inner region of a massive cluster forming in a cosmological LCDM simulation with a mass resolution of 2*10^6 Msun and before z=4.4 even 3*10^5 Msun. This is a billio…
Earth-mass dark-matter haloes as the first structures in the early Universe
Juerg Diemand, Ben Moore, Joachim Stadel
The Universe was nearly smooth and homogeneous before a redshift of z = 100, about 20 million years after the Big Bang. After this epoch, the tiny fluctuations imprinted upon the m…
