Dynamics of barred galaxies: effects of disk height
A. Klypin, O. Valenzuela, P. Colin +1
We study dynamics of bars in models of disk galaxies embeded in realistic dark matter halos. We find that disk thickness plays an important, if not dominant, role in the evolution…
The Milky Way Tomography with SDSS: II. Stellar Metallicity
Zeljko Ivezic, Branimir Sesar, Mario Juric +50
Using effective temperature and metallicity derived from SDSS spectra for ~60,000 F and G type main sequence stars (0.2<g-r<0.6), we develop polynomial models for estimating these…
The Formation of a Realistic Disk Galaxy in Lambda Dominated Cosmologies
F. Governato, L. Mayer, J. Wadsley +6
We simulate the formation of a realistic disk galaxy within the hierarchical scenario of structure formation and study its internal properties to the present epoch. We compare resu…
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…
The descendents of Lyman Break Galaxies in galaxy clusters: spatial distribution and orbital properties
F. Governato, S. Ghigna, B. Moore +3
We combine semi-analytical methods with a ultra-high resolution simulation of a galaxy cluster (of mass 2.3 10^14h-1Msolar, and 4 10^6 particles within its virial radius) formed in…
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…
The seeds of rich galaxy clusters in the Universe
F. Governato, C. M. Baugh, C. S. Frenk +4
The discovery of a population of young galaxies at an epoch when the universe was about one tenth of its current age has shed new light on the question of when and how galaxies for…
Resolving the Structure of Cold Dark Matter Halos
Ben Moore, Fabio Governato, Tom Quinn +2
We examine the effects of mass resolution and force softening on the density profiles of cold dark matter halos that form within cosmological N-body simulations. As we increase the…
The Local Group as a test of cosmological models
F. Governato, B. Moore, R. Cen +3
The dynamics of the Local Group and its environment provide a unique challenge to cosmological models. The velocity field within 5h-1 Mpc of the Local Group (LG) is extremely ``col…
