(Abridged) We describe a new iterative approach for the realization of equilibrium N-body systems for given density distributions. Our method uses elements of Schwarzschild's technique and of the made-to-measure method, but is based on a different principle. Starting with some initial assignment of particle velocities, we calculate their orbits using a flexible tree-based force algorithm in the stationary potential of the target density distribution. The difference of the time-averaged density… 

Applying Schwarzschild's orbit superposition method to barred or non-barred disc galaxies

We present an implementation of the Schwarzschild orbit superposition method which can be used for constructing self-consistent equilibrium models of barred or non-barred disc galaxies, or of

MAGI: many-component galaxy initializer

Providing initial conditions is an essential procedure for numerical simulations of galaxies. The initial conditions for idealised individual galaxies in $N$-body simulations should resemble observed

Dark matter with n-body numerical simulations

The fundamental concepts of N-body systems applied to the cosmological evolution of the ¤-Cold Dark Matter (¤CDM) model are presented and the Smoothed Particle Hydrodynamics method used for simulating the gas, star dynamics, and structure formation in these simulations is described.

The AREPO Public Code Release

This version contains a finite-volume magnetohydrodynamics algorithm on an unstructured, dynamic Voronoi tessellation coupled to a tree-particle-mesh algorithm for the Poisson equation either on a Newtonian or cosmologically expanding spacetime.

Simulations of ram-pressure stripping in galaxy-cluster interactions

Observationally, the quenching of star-forming galaxies appears to depend both on their mass and environment. The exact cause of the environmental dependence is still poorly understood, yet

Assessing the Jeans Anisotropic Multi-Gaussian Expansion method with the Illustris simulation

We assess the effectiveness of the Jeans-Anisotropic-MGE (JAM) technique with a state-of-the-art cosmological hydrodynamic simulation, the Illustris project. We perform JAM modelling on 1413

Quantifying Departures from Equilibrium with the Spherical Jeans Equation

Proper motions of collisionless, pointlike objects in a spherically symmetric system—for example, stars in a galaxy—can be used to test whether that system is in equilibrium, with no assumptions

galactics with gas

We present a new version of the GalactICS code that can generate self-consistent equilibrium galaxy models with a two-component stellar disc and a gas disc as well as a centrally-concentrated bulge

The quiescent phase of galactic disc growth

We perform a series of controlled N-body simulations of growing disc galaxies within non-growing, live dark matter haloes of varying mass and concentration. Our initial conditions include either a



Axisymmetric Three-Integral Models for Galaxies

We describe an improved, practical method for constructing galaxy models that match an arbitrary set of observational constraints, without prior assumptions about the phase-space distribution

On Schwarzschild's method for the construction of model galaxies

The method developed recently by Schwarzschild for the construction of model galaxies is formulated explicitly as a numerical method for the solution of the equations of galactic dynamics governing

The Cosmological simulation code GADGET-2

We discuss the cosmological simulation code GADGET-2, a new massively parallel TreeSPH code, capable of following a collisionless fluid with the N-body method, and an ideal gas by means of smoothed

Made-to-measure N-body systems

We describe an algorithm for constructing N-body realisations of equilibrium stellar systems. The algorithm complements existing orbit-based modelling techniques using linear programming or other

Generalized Schwarzschild’s method

We describe a new finite element method (FEM) to construct continuous equilibrium distribution functions (DFs) of stellar systems. The method is a generalization of Schwarzschild’s orbit

Nearly self-consistent disc–bulge–halo models for galaxies

We describe methods for setting up self-consistent disc-bulge-halo galaxy models. The bulge and halo distribution functions (DFs) are functions of E and L(z) only. The halo's flattening and rotation

A Universal Density Profile from Hierarchical Clustering

We use high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes. We find that all such profiles have the same shape,

Radial-orbit instability of a family of anisotropic Hernquist models with and without a supermassive black hole

We present a method to investigate the non-radial stability of a spherical anisotropic system that hosts a central supermassive black hole (SBH). Such systems have never been tested before for

Equilibrium Disk-Bulge-Halo Models for the Milky Way and Andromeda Galaxies

We describe a new set of self-consistent, equilibrium disk galaxy models that incorporate an exponential disk, a Hernquist model bulge, an NFW halo, and a central supermassive black hole. The models

The formation of galactic discs

We study the population of galactic discs expected in current hierarchical clustering models for structure formation. A rotationally supported disc with exponential surface density profile is assumed
