Thick Domain Wall Universes
We investigate the spacetime of a thick gravitating domain wall for a general potential V (Φ). Using general analytical arguments we show that all nontrivial solutions fall into two categories: those interpretable as an isolated domain wall with a cosmological event horizon, and those which are pure false vacuum de Sitter solutions. Although this latter solution is always unstable to the field ...
متن کاملCreating synthetic universes in a computer.
Cosmologists regularly generate synthetic universes of galaxies using computer simulations. Such catalogues have an essential role to play in the analysis and exploitation of current and forthcoming galaxy surveys. I review the different ways in which synthetic or 'mock' catalogues are produced and discuss the different physical processes that the models attempt to follow, explaining why it is ...
متن کاملCreating Virtual Universes Using Generative Adversarial Networks
Inferring model parameters from experimental data is a grand challenge in many sciences, including cosmology. This often relies critically on high fidelity numerical simulations, which are prohibitively computationally expensive. The application of deep learning techniques to generative modeling is renewing interest in using high dimensional density estimators as computationally inexpensive emu...
متن کاملThick self-gravitating plane-symmetric domain walls
We investigate a self-gravitating thick domain wall for a λΦ potential. The system of scalar and Einstein equations admits two types of non-trivial solutions: domain wall solutions and false vacuum-de Sitter solutions. The existence and stability of these solutions depends on the strength of the gravitational interaction of the scalar field, which is characterized by the number ǫ. For ǫ ≪ 1, we...
متن کاملThick Domain Walls around a Black Hole
We discuss the gravitationally interacting system of a thick domain wall and a black hole. We numerically solve the scalar field equation in the Schwarzschild spacetime and obtain a sequence of static axi-symmetric solutions representing thick domain walls. We find that, for the walls near the horizon, the Nambu–Goto approximation is no longer valid.
