Abstract:
Future ground-based GW detectors, such as the Einstein Telescope and Cosmic Explorer, will have unprecedented sensitivities that will allow us to study the entire population of stellar mass binary black holes in the Universe while the A+ and Voyager detectors will significantly improve over advanced LIGO & Virgo design sensitivities. To infer binary parameters from a GW signal we need accurate models of the gravitational waveform as a function of masses, spins, etc. Such waveform models are built from numerical relativity simulations and/or semi-analytical expressions in the inspiral. I will discuss up to which detector sensitivity current models will yield unbiased parameter estimates for typical binary black hole systems and what biases we can to expect beyond.
