Novel Adaptive softening for collisionless N-body simulations: Eliminating spurious halos
Alexander Hobbs, Justin Read, Oscar Agertz +2
We describe a NOVel form of Adaptive softening (NovA) for collisionless -body simulations, implemented in the Ramses adaptive mesh refinement code. We introduce a refinement cri…
On the orbital and internal evolution of cluster galaxies
Francesca Iannuzzi, Klaus Dolag
Galaxies inhabiting a cluster environment experience significant evolution in their orbital motions throughout time; this is accompanied by changes in the anisotropy parameter, mea…
Adaptive gravitational softening in GADGET
Francesca Iannuzzi, Klaus Dolag
Cosmological simulations of structure formation follow the collisionless evolution of dark matter starting from a nearly homogeneous field at early times down to the highly cluster…
Baryon history and cosmic star formation in non-Gaussian cosmological models: numerical simulations
Umberto Maio, Francesca Iannuzzi
We present the first numerical, N-body, hydrodynamical, chemical simulations of cosmic structure formation in the framework of non-Gaussian models. We study the impact of primordia…
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…
Imprints of primordial non-Gaussianities in X-ray and SZ signals from galaxy clusters
M. Roncarelli, L. Moscardini, E. Branchini +4
Several inflationary models predict the possibility that the primordial perturbations of the density field may contain a degree of non-Gaussianity which would influence the subsequ…
Large-scale non-Gaussian mass function and halo bias: tests on N-body simulations
M. Grossi, L. Verde, C. Carbone +5
The description of the abundance and clustering of halos for non-Gaussian initial conditions has recently received renewed interest, motivated by the forthcoming large galaxy and c…
