A High Throughput Workflow Environment for Cosmological Simulations
Brandon M. S. Erickson, Raminderjeet Singh, August E. Evrard +6
The next generation of wide-area sky surveys offer the power to place extremely precise constraints on cosmological parameters and to test the source of cosmic acceleration. These…
Large Synoptic Survey Telescope: Dark Energy Science Collaboration
LSST Dark Energy Science Collaboration
This white paper describes the LSST Dark Energy Science Collaboration (DESC), whose goal is the study of dark energy and related topics in fundamental physics with data from the La…
Rhapsody. II. Subhalo Properties and the Impact of Tidal Stripping From a Statistical Sample of Cluster-Size Halos
Hao-Yi Wu, Oliver Hahn, Risa H. Wechsler +2
We discuss the properties of subhalos in cluster-size halos, using a high-resolution statistical sample: the Rhapsody simulations introduced in Wu et al. (2012). We demonstrate tha…
Halo-to-Halo Similarity and Scatter in the Velocity Distribution of Dark Matter
Yao-Yuan Mao, Louis E. Strigari, Risa H. Wechsler +2
We examine the Velocity Distribution Function (VDF) in dark matter halos from Milky Way to cluster mass scales. We identify an empirical model for the VDF with a wider peak and a s…
The Dark Energy Spectrometer (DESpec): A Multi-Fiber Spectroscopic Upgrade of the Dark Energy Camera and Survey for the Blanco Telescope
F. Abdalla, J. Annis, D. Bacon +29
We describe an initiative to build and use the Dark Energy Spectrometer (DESpec), a wide-field spectroscopic survey instrument for the Blanco 4 meter telescope at Cerro Tololo Inte…
Rhapsody. I. Structural Properties and Formation History From a Statistical Sample of Re-simulated Cluster-size Halos
Hao-Yi Wu, Oliver Hahn, Risa H. Wechsler +2
We present the first results from the Rhapsody cluster re-simulation project: a sample of 96 "zoom-in" simulations of dark matter halos of 10^14.8 +- 0.05 Msun/h, selected from a 1…
