Computational General Relativistic Astrophysics - Black Holes, Neutron Stars and Gamma Ray Bursts
Professor, Washington University
General Relativistic Astrophysics---astrophysics that involves strong and dynamical gravitational fields requiring the full Einstein equations for its understanding---is becoming an exciting area of research, due to the large amount of data in high energy astronomy, and to the great promise of gravitational wave astronomy. In particular, Computational General Relativistic Astrophysics, with the recent stunning increases in computer power, may hold the key to the understanding of many observations in high-energy astronomy and gravitational wave astronomy.
In this talk the speaker will discuss two major projects in this direction: the NASA Neutron Star Grand Challenge Project aiming at the development of a multi-purpose 3D code "GR3D" for general relativistic astrophysics, and the NSF Astrophysics Simulation Collaboratory (ASC) Project aiming at the development of a computational infrastructure building on top of this GR3D code to facilitate large-scale simulations using state-of-the-art massively parallel computational technologies. Black hole, neutron star and gamma ray burst simulations carried out in these projects will be discussed.
