Black holes are the most interesting and extraordinary objects
predicted by Einstein's general relativity. No longer regarded as
science fiction, black holes are now expected to be rather common
astrophysical objects, occurring even in pairs. There is increasing
astronomical evidence of black hole binaries in many galaxies, formed
long before by the collapse of huge amounts of matter. Some
interesting simulations indicate that these systems may also be
commonly generated in globular clusters. [

In investigating the complete physical evolution of black-hole
binaries, the UTB NR group has made great progress in several areas:
- The study of physically realistic and interesting initial data to
model the start of the evolution process;
- The evolution of binary initial data using advanced formulations
of Einstein's equations, dynamic gauges, and moving punctures;
- The Lazarus project , which extracts the gravitational radiation
from late-time full-3D binary evolutions, and evolves it in a stable
and accurate 2D Teukolsky evolution.
- The calculation of gravitational radiation reaction for interacting
massive bodies.
