Nonlinear Structure and Halo Formation
Nonlinear Structure and Halo Formation
This chapter studies the evolution of perturbations in the nonlinear regime. It focuses for the most part on analytic models that shed light on the physical processes involved. The advent of computer technology has made numerical studies of nonlinear evolution almost routine, and many of today's theoretical calculations follow this path. The analytic approaches described here inform these calculations, but the numerical simulations help to sharpen this chapter's conclusions and predictions. The chapter discusses this synergy and describes “semianalytic” models that can be written analytically but whose ultimate justification lies in their good agreement with numerical simulations. It also describes the fundamental aspects of computational methods.
Keywords: nonlinear structure, halo formation, perturbations, analytic models, nonlinear evolution, numerical simulations, semianalytic models, computational methods
