Ellery Ames and Håkan Andréasson both seem very pleased with our new results, but pointing at different branches?
It’s always exciting when I get together with my colleagues Håkan Andréasson and Ellery Ames, and good things tend to happen. Our work could be summarized as solving the Einstein-Vlasov equations and trying to find interesting things, such as black holes, geons and cosmic strings. Previously, we found some interesting galaxies, in particular the Hoag-like object depicted below.
