Using Perturbative Least Action to Run N Body Simulations Back in Time

Astrophysics 2007-05-23 v1

Abstract

In this report, we present a new method for reconstructing N body initial conditions from a proscribed final density field. This method, Perturbative Least Action (PLA) is similar to traditional least action approaches, except that orbits of particles are found as expansions around previously determined and physically motivated orbits.
