Matter power spectrum and the challenge of percent accuracy (2015, methodology): “The gravity code Pkdgrav3 (an earlier version of which is described in Stadel 2001) is based on a binary tree algorithm using fifth order fast multipole expansion of the gravitational potential (using cell-cell interactions making it an O(N) gravity calculation method).”
THE M31 VELOCITY VECTOR. II. RADIAL ORBIT TOWARD THE MILKY WAY AND IMPLIED LOCAL GROUP MASS (2012, methodology): “The model is evolved using the PKDGRAV tree N-body code (Stadel 2001) for nearly 1 Gyr, until it forms orbital wraps closely resembling features in M31 including the GSS itself, and the NE and W shelves.”
Size-frequency distributions of fragments from SPH/N-body simulations of asteroid impacts: Comparison with observed asteroid families (2007, methodology): “Once the impact phase of the simulations is complete (ejecta flow fields established with no further fragmentation/damage), the outcomes of the SPH models are handed off as the initial conditions for N -body gravitational simulations using the code pkdgrav (Richardson et al., 2000; Leinhardt and Ric”
Numerical simulations of the dark universe: State of the art and the next decade (2012, unknown): “Pkdgrav2 [244] is a prominent example of a pure tree code, and it uses FFM.”
A new method to quantify the effects of baryons on the matter power spectrum (2015, methodology): “We use N -body simulations from previous work [15, 33] (performed with Pkdgrav3 [34]) with box sizes of L = 32, 64 128, 256 Mpc/h and particle numbers of N = 64 128, 256,”
Full numerical simulations of catastrophic small body collisions (2008, methodology): “The gravitational reaccumulation phase of the collision is modeled using the N-body gravity code, pkdgrav (Richardson et al., 2000; Leinhardt et al., 2000; Stadel, 2001), the same code used in previous hybrid studies.”
Cosmology and Fundamental Physics with the Euclid Satellite (2012, methodology): “N -body simulations are performed by using a modified version of pkdgrav [859] able to handle any DE state equation w(a), with N(3) = 256(3) particles in a box with side L = 256h−1 Mpc.”
Clumps in the outer disk by disk instability: Why they are initially gas giants and the legacy of disruption (2009, methodology): “Particles are flagged as fragment members using SKID (Stadel, 2001), which groups particles according to density gradients and then completes an iterative unbind for each particle in the group.”
Quantifying baryon effects on the matter power spectrum and the weak lensing shear correlation (2018, methodology): “The N -body simulation is run with Pkdgrav3 [35, 36] based on the cosmological parameters Ωm = 0.”
