Research in the Relativity and Gravitation Group at UIB covers a wide range of topics in numerical relativity, gravitational wave astronomy, mathematical relativity and computational methods. As a member of the LIGO Scientific Collaboration (LSC), and the GEO, NINJA-2 and NRAR collaborations, a focus point is provided by gravitational wave science, where we are involved in analysing observational data, and in the theoretical modeling of black holes and other phenomena in Einstein’s general relativity.
Both in gravitational wave data analysis and in simulating black holes, our work often relies on supercomputing and developing scientific software.
Contributions to open source astrophysics software include:
- LSC Algorithm Library and the Einstein@Home project
- Data analysis tools and software that are currently being used in GEO and LIGO for astrophysical searches of spinning neutron stars and the sources of gamma-ray-bursts.
- Einstein toolkit, an open, community developed software infrastructure for relativistic astrophysics.
- Kranc, a Mathematica application which turns a tensorial description of a time dependent partial differential equation into a module for the Cactus Computational Toolkit
