Halo Assembly Bias in Hierarchical Structure Formation
Neal Dalal, Martin White, J. Richard Bond +1
We investigate the origin of halo assembly bias, the dependence of halo clustering on assembly history. We relate halo assembly to peak properties measured in the Lagrangian space…
GRAvitational COSmology (GRACOS) code release announcement, for version 1.0.1a9
Alexander Shirokov
This is to announce a recent release of version 1.0.1a9 of parallel load balanced adaptive P3M cosmological N-body code named GRACOS. The code has been under development over years…
Gravitational Softening and Adaptive Mass Resolution
Alexander Shirokov
Pairwise forces between particles in cosmological N-body simulations are generally softened to avoid hard collisions. Physically, this softening corresponds to treating the particl…
The imprints of primordial non-gaussianities on large-scale structure: scale dependent bias and abundance of virialized objects
Neal Dalal, Olivier Doré, Dragan Huterer +1
We study the effect of primordial nongaussianity on large-scale structure, focusing upon the most massive virialized objects. Using analytic arguments and N-body simulations, we ca…
GRACOS: Scalable and Load Balanced P3M Cosmological N-body Code
Alexander Shirokov, Edmund Bertschinger
We present a parallel implementation of the particle-particle/particle-mesh (P3M) algorithm for distributed memory clusters. The GRACOS (GRAvitational COSmology) code uses a hybrid…
