Compact Binary Coalescence Searches

The research of the compact binary coalescence (CBC) group is concerned with gravitational waves from binary systems consisting of compact objects (black holes and/or neutron stars) in a compact orbit around each other.

The activities of the group are closely connected with the analysis of data from the LIGO, Virgo and GEO600 detectors. The research interests of the group ranges from observational searches of data from these detectors, developing new analysis methods and software, understanding and extending the gravitational wave signal models, and theoretical aspects of black hole physics relevant to such binary systems.

Our group contributes to various projects, aiming at the gravitational-wave detection and characterization of compact binary coalescences. These projects include:

  • Searching for binary black hole coalescences using the inspiral, merger and ringdown phases
  • Porting existing CBC codes and developing new search codes for General Purpose Computation on Graphics Processing Units (GPUs)
  • Improving the theoretical framework of CBC searches, e.g. via calculations of a parameter space metric, faster significance estimates, and the inclusion of spin and precession effects
  • Theoretical work on black holes
