Black hole lattices are an interesting subset of inhomogeneous cosmologies. These are exact, fully-relativistic treatments of universes with a discretised matter content. We generalise existing lattices to include a cosmological constant and structure formation. For each new generalisation, we find a common behaviour of tending towards FLRW-like as the number of masses is increased, and for...

We generate initial data for vacuum spacetimes (possibly with cosmological constant) via the conformal method, with a three sphere or a ”three- donut” (the product of a two-sphere with a circle) as "seed metrics". Our motivation comes from black-hole-lattice cosmology. However, in contrast to known schemes for constructing corresponding data, we do not allow for punctures, which prevents us...
