Cosmological Simulations of Galaxy Formation I: Star Formation, Feedback, Resolution and Matching the Tully--Fisher Relation (among other things)
Fabio Governato, Greg Stinson, J. Wadsley +1
We used fully cosmological, high resolution N-body+SPH simulations to follow the formation of disk galaxies with a rotational velocity between 140 and 280 Km/sec in a Lambda CDM un…
Frequently Asked Questions on the Luminosity--Temperature relation in Groups and Clusters
Fabio Governato
Efforts to understand the deviation of the L--T relation from a simple scaling law valid for clusters and groups have triggered a number of interesting studies on the subject. Tech…
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 Structure and Dynamics of Cold Dark Matter Halos
Ben Moore, Sebastiano Ghigna, Fabio Governato +3
We investigate the internal structure of cold dark matter halos using high resolution N-body simulations. As the mass and force resolution are increased, halo density profiles beco…
On the origin of early type galaxies and the evolution of the interaction rate in the field
F. Governato, Jeffrey P. Gardner, J. Stadel +2
Using cosmological N-body simulations of critical (SCDM) and open (Omega_0=0.3, OCDM) cold dark matter models we have identified dark matter halos which are associated with the pro…
Small groups of Galaxies as Cosmological Clocks
P. Tozzi, F. Governato, A. Cavaliere
We study the formation and evolution of small groups of galaxies using new Monte Carlo simulations. These are directly based on the random walk approach to the statistics of conden…
