  • Initial data for a single boosted black hole is constructed that analytically contains no initial transient (junk) gravitational radiation and is adapted to the moving punctures gauge conditions. The properties of this data are investigated in detail. It is found to be generally superior to canonical Bowen-York data and, when implemented numerically in simulations, yields orders of magnitude less junk gravitational radiation content and more accurate black hole velocities. This allows for modeling of black holes that are boosted faster than previously possible. An approximate superposition of the data is used to demonstrate how a binary black hole system can be constructed to retain the advantages found for the single black hole. Extensions to black holes with spin are considered.
