Banks of templates for directed searches of gravitational waves from spinning neutron stars

Understand

We construct efficient banks of templates suitable for directed searches of almost monochromatic gravitational waves originating from spinning nuetron stars in our Galaxy in data being collected by currently operating interferometric detectors.

• We thus assume that the position of the gravitational-wave source in the sky is known, but we do not assume that the wave's frequency and its derivatives are a priori known.
• In the construction we employ simplified model of the signal with constant amplitude and phase which is a polynomial function of time.
• All our template banks enable usage of the fast Fourier transform algorithm in the computation of the maximum-likelihood F-statistic for nodes of the grids defining the bank.
