Computational Relativity and Gravitation at Petascale: Simulating and Visualizing Astrophysically Realistic Compact Binaries

Manuela Campanelli, Rochester Institute of Technology

Usage Details

This project focuses on three topics within the field of numerical relativity and relativistic astrophysics:

• The mergers of black-hole binaries with very small ratios and very high spins, for which the differing spatial scales and high accuracy required exceed the abilities of terascale resources.
• the long-term evolution of merging black hole-neutron star and neutron star-neutron star systems for many orbits prior to merger. Here, the focus is on properly resolving small-scale features while minimizing numerical errors that inevitably build up over time.
• the disks that either form around black holes as a result of black hole-neutron star mergers and neutron star-neutron star mergers, or exist prior to merger in the case of merging black hole binaries. Here we face both a wide range of time and spatial scales that will require new highly accurate and efficient mesh refinement techniques to model properly.
