Understanding initial data for black hole collisions

  title={Understanding initial data for black hole collisions},
  author={Carlos O. Lousto and Richard H. Price},
Numerical relativity, applied to collisions of black holes, starts with initial data for black holes already in each other’s strong field. For the initial data to be astrophysically meaningful, it must approximately represent conditions that evolved from holes originally at large separation. The initial hypersurface data typically used for computation is based on mathematically simplifying prescriptions, such as conformal flatness of the 3-geometry and longitudinality of the extrinsic curvature… CONTINUE READING
