Status Report on the Numerical Relativity/Analytical Relativity collaboration — •Ian Hinder — Max Planck Institute for Gravitational Physics (Albert Einstein Institute), Potsdam, Germany

I report on the current status of the Numerical Relativity/Analytical Relativity (NR/AR) collaboration. In this project, a collaboration between 14 numerical relativity (NR) and 7 analytical relativity (AR) groups, we aim to use gravitational waveforms from NR simulations of binary black holes to construct accurate analytical templates to be used in the search for gravitational waves with the LIGO and Virgo detectors. I describe our target requirements on waveform length and accuracy, as well as the techniques we use to process the NR data into a form suitable for use with analytical models. Simulations from the first stage, encompassing mostly aligned-spin configurations, are complete, and I present an overview of the numerical results obtained so far.
