Hybrid geometric-random template placement algorithm for gravitational wave searches from compact binary coalescences

Understand

Astrophysical compact binary systems consisting of neutron stars and blackholes are an important class of gravitational wave (GW) sources for advanced LIGO detectors.

• Accurate theoretical waveform models from the inspiral, merger and ringdown phases of such systems, are used to filter detector data under the template based matched filtering paradigm.
• An efficient grid over the parameter space at a fixed minimal match has a direct impact on the overall time taken by these searches.
• We present a new hybrid geometric-random template placement algorithm for signals described by two masses and one spin magnitude parameters.
