Gravitational-wave measurements from binary black holes and their dependency on waveform models — •Frank Ohme — Cardiff University, Cardiff, United Kingdom — Max-Planck-Institut für Gravitationsphysik, Potsdam/Hannover, Germany

Successfully detecting and interpreting gravitational waves from coalescing black-hole binaries requires a detailed model of the signals to be expected. With a combination of analytical approximations and full-relativistic numerical simulations it only recently became possible to predict the entire signal emitted by an inspiraling and merging binary, even in the complicated case of precessing black hole spins. However, these models are not free of errors, and I will summarize in this talk how to construct state-of-the-art waveform models, how to assess their errors and estimate the impact those may have on actual gravitational-wave measurements.
