Phase-space structure in the local dark matter distribution and its signature in direct detection experiments
Mark Vogelsberger, Amina Helmi, Volker Springel +6
We study predictions for dark matter phase-space structure near the Sun based on high-resolution simulations of six galaxy halos taken from the Aquarius Project. The local DM densi…
Hydrodynamical N-body simulations of coupled dark energy cosmologies
Marco Baldi, Valeria Pettorino, Georg Robbers +1
If the accelerated expansion of the Universe at the present epoch is driven by a dark energy scalar field, there may well be a non-trivial coupling between the dark energy and the…
Cross-Correlation between Damped Ly-alpha Systems and Ly-break Galaxies in Cosmological SPH Simulations
Tae Song Lee, Kentaro Nagamine, Lars Hernquist +1
We calculate the cross-correlation function (CCF) between damped Ly-a systems (DLAs) and Lyman break galaxies (LBGs) using cosmological hydrodynamic simulations at z=3. We compute…
An implementation of radiative transfer in the cosmological simulation code GADGET
M. Petkova, V. Springel
We present a novel numerical implementation of radiative transfer in the cosmological smoothed particle hydrodynamics (SPH) simulation code {\small GADGET}. It is based on a fast,…
The Formation and Survival of Discs in a Lambda-CDM Universe
Cecilia Scannapieco, Simon D. M. White, Volker Springel +1
We study the formation of galaxies in a Lambda-CDM Universe using high resolution hydrodynamical simulations with a multiphase treatment of gas, cooling and feedback, focusing on t…
Phase-space structures II: Hierarchical Structure Finder
M. Maciejewski, S. Colombi, V. Springel +2
A new multi-dimensional Hierarchical Structure Finder (HSF) to study the phase-space structure of dark matter in N-body cosmological simulations is presented. The algorithm depends…
