Nonlinear stability of Einstein-de Sitter universes
Louie Bernhardt, David Fajman, Zoe Wyatt
The Einstein-de Sitter universe is the prevailing model used in cosmology to describe the cold dark matter-dominated epoch of the universe. This model is a spatially homogeneous an…
Non-linear stability of the matter dominated universe
David Fajman, Elliot Marshall
We numerically study non-linear perturbations of the Einstein-de Sitter spacetime as a solution to the Gowdy-symmetric Einstein-Euler system for a polytropic equation of state. The…
Landau damping on expanding backgrounds
David Fajman, Liam Urban
We analyse the effect of expansion in Newtonian cosmology on the asymptotic behaviour of charged self-interacting plasmas close to Poisson equilibria. To this end, we study the Vla…
A critical threshold for the cosmological Euler-Poisson system
David Fajman, Maciej Maliborski, Maximilian Ofner +2
We consider the gravitational Euler-Poisson system with a linear equation of state on an expanding cosmological model of the Universe. The expansion of the spatial sections introdu…
Charged black holes surrounded by shells of charged particles
David Fajman, Hannah Seer
We construct new static solutions to the Einstein-Vlasov-Maxwell system. These solutions model Reissner-Nordstrom-type black holes with surrounding shells of charged matter.
Cosmic Censorship near FLRW spacetimes with negative spatial curvature
David Fajman, Liam Urban
We consider general initial data for the Einstein scalar-field system on a closed -manifold which is close to data for a Friedman-Lemaître-Robertson-Walker solution wi…
