The Numerical Relativity group at UT Brownsville is a major part of
the
Center for Gravitational-Wave
Astronomy (CGWA). Our research focuses on the development and
application of numerical relativity tools and perturbative methods to
problems of current astrophysical interest: for example, supercomputer
simulations of binary black-hole coalescences, modeling of small
compact objects orbiting a supermassive black hole etc, and assisting
in gravitational wave data analysis efforts.
Our research in full 3+1-dimensional Numerical Relativity addresses
important open problems concerning the development and use of tools to
study:
- Realistic initial data for astrophysical binary black-hole systems
- Stable and accurate evolution systems for Einstein's equations
- Radiation identification and extraction
We also have a strong effort in perturbative methods. The Lazarus project is aimed at
providing a seamless interface between full-numerical 3+1 simulations
and perturbative 2+1 Teukolsky evolutions at late times.
Models of small compact objects (e.g. a neutron star or a black hole)
in orbit around a much larger black hole can also be constructed via
the use of perturbation methods. The calculation of gravitational
radiation reaction plays an important part in this area and
members of our group are dedicating considerable effort to solving
this problem.
