We review the formalism and applications of non-linear perturbation theory (PT) to
understanding the large-scale structure of the Universe. We first discuss the dynamics of …

▪ Abstract Cosmic structure has formed as a result of gravitational amplification of primordial
density fluctuations together with the action of other physical processes (adiabatic gas …

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 …

We describe the newly written code GADGET which is suitable both for cosmological
simulations of structure formation and for the simulation of interacting galaxies. GADGET …

This book discusses in detail all the relevant numerical methods for the classical N-body
problem. It demonstrates how to develop clear and elegant algorithms for models of …

Mergers of black hole binaries are expected to release large amounts of energy in the form
of gravitational radiation. However, binary evolution models predict merger rates that are too …

We study the growth rate of stars via stellar collisions in dense star clusters, calibrating our
analytic calculations with direct N-body simulations of up to 65,536 stars, performed on the …

Planetary accretion from planetesimals to protoplanets is investigated using three-
dimensional N-body simulations. The effect of gas drag due to solar nebula is included and …

We investigate the formation of protoplanet systems from planetesimal disks by global (N=
5000 and 10,000 and 0.5 AU< a< 1.5 AU, where N is the number of bodies and a is the …

The evolution of young compact star clusters is studied using N-body simulations in which
both stellar evolution and physical collisions between stars are taken into account. The initial …
