Dark matter halo occupation: environment and clustering
Rupert Croft, Tiziana Di Matteo, Nishikanta Khandai +3
We use a large dark matter simulation of a LambdaCDM model to investigate the clustering and environmental dependence of the number of substructures in a halo. Focusing on redshift…
Terapixel imaging of cosmological simulations
Yu Feng, Rupert A. C. Croft, Tiziana Di Matteo +8
The increasing size of cosmological simulations has led to the need for new visualization techniques. We focus on Smoothed Particle Hydrodynamical (SPH) simulations run with the GA…
Haloes gone MAD: The Halo-Finder Comparison Project
Alexander Knebe, Steffen R. Knollmann, Stuart I. Muldrew +34
[abridged] We present a detailed comparison of fundamental dark matter halo properties retrieved by a substantial number of different halo finders. These codes span a wide range of…
Three-Point Correlation Functions of SDSS Galaxies: Constraining Galaxy-Mass Bias
Cameron K. McBride, Andrew J. Connolly, Jeffrey P. Gardner +5
We constrain the linear and quadratic bias parameters from the configuration dependence of the three-point correlation function (3PCF) in both redshift and projected space, utilizi…
Detecting neutral hydrogen in emission at redshift z ~ 1
Nishikanta Khandai, Shiv K. Sethi, Tiziana Di Matteo +4
We use a large N-body simulation to examine the detectability of HI in emission at redshift z ~ 1, and the constraints imposed by current observations on the neutral hydrogen mass…
Astronomy in the Cloud: Using MapReduce for Image Coaddition
Keith Wiley, Andrew Connolly, Jeff Gardner +5
In the coming decade, astronomical surveys of the sky will generate tens of terabytes of images and detect hundreds of millions of sources every night. The study of these sources w…
