NR consists in the solution of Einstein’s Equation of general relativity, which governs the evolution of matter and energy on cosmological scales, and in systems where there are strong gravitational effects, such as around black holes. To date, NR has mainly been used for simulating binary black hole and neutron star mergers like those detected recently by LIGO. Its use as a tool in fundamental problems of gravity and cosmology is novel, but rapidly gaining interest. The author investigates the initial condition problem in early universe cosmology – whether an inflationary expansion period could have “got going” from initially inhomogeneous conditions – and identifies criteria for predicting the robustness of particular models. Further, it develops state-of-the-art numerical relativity tools in order to address this question, which are now publicly available.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053CosmologyGravitationPhysicsCosmologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P22049Classical and Quantum Gravitation, Relativity Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P19070Numerical and Computational Physics, Simulationhttps://scigraph.springernature.com/ontologies/product-market-codes/P19021Cosmology.Gravitation.Physics.Cosmology.Classical and Quantum Gravitation, Relativity Theory.Numerical and Computational Physics, Simulation.530.11015153Clough Katyauthttp://id.loc.gov/vocabulary/relators/aut1060608BOOK9910300548003321Scalar Fields in Numerical General Relativity2514572UNINA
