Full-Sky Weak Lensing Simulation with 70 Billion Particles
Romain Teyssier, Sandrine Pires, Simon Prunet +7
We have performed a 70 billion dark-matter particles N-body simulation in a 2 Gpc periodic box, using the concordance, cosmological model as favored by the latest WMAP3 re…
Initial Conditions for Large Cosmological Simulations
S. Prunet, C. Pichon, D. Aubert +3
This technical paper describes a software package that was designed to produce initial conditions for large cosmological simulations in the context of the Horizon collaboration. Th…
Numerical investigation of lenses with substructures using the perturbative method
Sébastien Peirani, Christophe Alard, Christophe Pichon +2
We present a statistical study of the effects induced by substructures on the deflection potential of dark matter halos in the strong lensing regime. This investigation is based on…
A radiative transfer scheme for cosmological reionization based on a local Eddington tensor
Dominique Aubert, Romain Teyssier
A radiative transfer scheme is presented, based on a moment description of the equation of radiative transfer and the so-called ``M1 closure model'' for the Eddington tensor. This…
Smooth Particle Lensing
Dominique Aubert, Adam Amara, R. Benton Metcalf
We present a numerical technique to compute the gravitational lensing induced by simulated haloes. It relies on a 2D-Tree domain decomposition in the lens plane combined with a des…
The origin and implications of dark matter anisotropic cosmic infall on ~L* haloes
Dominique Aubert, Christophe Pichon, Stephane Colombi
We measure the anisotropy of dark matter flows on small scales in the near environment of haloes using a large set of simulations. We rely on two different approaches to quantify t…
