Gravitational collapse on the scalar field dark matter model: The numerical relativity approach |
|
Abstract |
We study the formation of structure in the Universe assuming that dark matter can be described by a scalar field φ with a potential V(φ) = m^2φ^2/2. We derive the evolution equations of the scalar field in the linear regime of perturbations. In order to study the nonlinear regime, we use the spherical collapse model. In this work, we adapt a numerical relativity code to evolve cosmological scenarios and deal with the nonlinear problem of structure formation in situations where a description of matter in terms of scalar fields is necessary. |
