The Dependence of Halo Clustering on Halo Formation History, Concentration, and Occupation
Risa H. Wechsler, Andrew R. Zentner, James S. Bullock +2
We investigate the dependence of dark matter halo clustering on halo formation time, density profile concentration, and subhalo occupation number, using high-resolution numerical s…
Constraining the Projected Radial Distribution of Galactic Satellites with the Sloan Digital Sky Survey
Jacqueline Chen, Andrey V. Kravtsov, Francisco Prada +5
We use the Sloan Digital Sky Survey (SDSS) spectroscopic sample to constrain the projected radial distribution of satellites around isolated ~ L* galaxies. We employ mock galaxy ca…
Modeling Luminosity-Dependent Galaxy Clustering Through Cosmic Time
Charlie Conroy, Risa H. Wechsler, Andrey V. Kravtsov
We employ high-resolution dissipationless simulations of the concordance LCDM cosmology to model the observed luminosity dependence and evolution of galaxy clustering through most…
Constraining Dark Energy with the Dark Energy Survey: Theoretical Challenges
James Annis, Sarah Bridle, Francisco J. Castander +14
The Dark Energy Survey (DES) will use a new imaging camera on the Blanco 4-m telescope at CTIO to image 5000 square degrees of sky in the South Galactic Cap in four optical bands,…
Dark Energy Studies: Challenges to Computational Cosmology
James Annis, Francisco J. Castander, August E. Evrard +12
The ability to test the nature of dark mass-energy components in the universe through large-scale structure studies hinges on accurate predictions of sky survey expectations within…
The Shape of Galaxy Cluster Dark Matter Haloes: Systematics of Its Imprint on Cluster Gas, and Comparison to Observations
Ricardo A. Flores, Brandon Allgood, Andrey V. Kravtsov +3
(Abridged) We study predictions for galaxy cluster observables that can test the statistics of dark matter halo shapes expected in a flat LCDM universe. We present a simple analyti…
