Intracluster stellar population properties from N-body cosmological simulations -- I. Constraints at
N. R. Napolitano, M. Pannella, M. Arnaboldi +8
We use a high resolution collisionless simulation of a Virgo--like cluster in a CDM cosmology to determine the velocity and clustering properties of the diffuse stellar componen…
Constraining Lambda using cluster quadrupoles
A. Maccio`, A. Gardini, S. Ghigna +1
We examine how the statistics of the quadrupoles of (projected) cluster masses can discriminate between flat cold dark matter (CDM) universes with or without a cosmological constan…
Dark matter in Draco and the Local Group: Implications for direct detection experiments
Ben Moore, Carlos Calcaneo-Roldan, Joachim Stadel +4
We use a cosmological simulation of the Local Group to make quantitative and speculative predictions for direct detection experiments. Cold dark matter (CDM) halos form via a compl…
Is Cold Dark Matter Still a Strong Buy? The Lesson from Galaxy Clusters
Fabio Governato, Sebastiano Ghigna, Ben Moore
For the last few years the Cold Dark Matter model (ticker: CDM), has been the dominant theory of structure formation. We briefly review the recent advancements and predictions of t…
Density profiles and substructure of dark matter halos: converging results at ultra-high numerical resolution
Sebastiano Ghigna, Ben Moore, Fabio Governato +3
Can N-body simulations reliably determine the structural properties of dark matter halos? Focussing on a Virgo-sized galaxy cluster, we increase the resolution of current ``high re…
Dark Matter Substructure in Galactic Halos
Ben Moore, Sebastiano Ghigna, Fabio Governato +4
We use numerical simulations to examine the substructure within galactic and cluster mass halos that form within a hierarchical universe. Clusters are easily reproduced with a stee…
