Tidal debris of dwarf spheroidals as a probe of structure formation models
Lucio Mayer, Ben Moore, Thomas Quinn +2
Recent observations suggest that Carina and other nearby dwarf spheroidal galaxies are surrounded by unbound stars tidally stripped by the Milky Way. We run high-resolution N-Body…
Predicting the number, spatial distribution and merging history of dark matter haloes
P. Monaco, T. Theuns, G. Taffoni +3
We present a new algorithm (PINOCCHIO, PINpointing Orbit-Crossing Collapsed HIerarchical objects) to predict accurately the formation and evolution of individual dark matter haloes…
Pre-heating the ICM in high resolution simulations: the effect on the gas entropy
S. Borgani, F. Governato, J. Wadsley +5
We present results from high-resolution Tree+SPH simulations of galaxy clusters and groups, aimed at studying the effect of non-gravitational heating on the entropy of the ICM. We…
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…
The Metamorphosis of Tidally Stirred Dwarf Galaxies
Lucio Mayer, Fabio Governato, Monica Colpi +5
We present results from high-resolution N-Body/SPH simulations of rotationally supported dwarf irregular galaxies moving on bound orbits in the massive dark matter halo of the Milk…
