Contribution

The paper presents new data analysis tools for all-sky continuous gravitational-wave searches applicable to multiple detector types, enhancing detection capabilities.

Findings

Able to perform a 2-day coherent search on resonant bar data

No loss of signals with amplitude > 2.8×10^{-23}

Applicable to both resonant bar and laser interferometric detectors

Abstract

We develop a set of data analysis tools for a realistic all-sky search for continuous gravitational-wave signals. The methods that we present apply to data from both the resonant bar detectors that are currently in operation and the laser interferometric detectors that are in the final stages of construction and commissioning. We show that with our techniques we shall be able to perform an all-sky 2-day long coherent search of the narrow-band data from the resonant bar EXPLORER with no loss of signals with the dimensionless amplitude greater than $2.8\times10^{-23}$.
