We investigate the computational requirements for all-sky, all-frequency searches for gravitational waves from spinning neutron stars, using archived data from interferometric gravitational wave detectors such as LIGO. These sources are expected to be weak, so the optimal strategy involves coherent accumulation of signal-to-noise using Fourier transforms of long stretches of data (months to years). Earth-motion-induced Doppler shifts, and intrinsic pulsar spindown, will reduce the narrow-band…

Searching for gravitational waves from pulsars in binary systems: An all-sky search
Non axisymmetrical neutron stars emit continuous gravitational waves. The periodicity of the system allows for the improvement of the signal-to-noise ratio by integrating the signal over time. Many
Banks of templates for all-sky narrow-band searches of gravitational waves from spinning neutron stars
We construct efficient banks of templates suitable for all-sky narrow-band searches of almost monochromatic gravitational waves originating from spinning neutron stars in our Galaxy in data collected
A resampling algorithm to detect continuous gravitational-wave signals from neutron stars in binary systems
A rapidly rotating neutron star (NS) with non-axisymmetric deformations is an interesting type of continuous gravitational-Wave (CW) source for the advanced LIGO–Virgo detectors. Within the
Einstein@Home search for periodic gravitational waves in LIGO S4 data
A search for periodic gravitational waves, from sources such as isolated rapidly spinning neutron stars, was carried out using 510 h of data from the fourth LIGO science run (S4). The search was for
Flat parameter-space metric for all-sky searches for gravitational-wave pulsars
All-sky, broadband, coherent searches for gravitational-wave pulsars are computationally limited. It is therefore important to make efficient use of available computational resources, notably by
Bayesian searches for gravitational waves from pulsars
Methods for searching for periodic gravitational wave signals from triaxial pulsars using interferometric gravitational wave detectors have been developed. Since the gravitational wave signals from
Search for periodic gravitational wave sources with the Explorer detector
We have developed a procedure for the search of signals from periodic sources in the data of gravitational wave detectors. We report here the analysis of one year of data from the resonant detector
Phase decomposition of the template metric for continuous gravitational-wave searches
This paper shows a general phase decomposition technique able to make the template metric analytically computable and shows how this variables can be employed to distinguish in a robust way among astrophysical signals and non-stationary noise artifacts that may affect analysis pipelines.
Data analysis of gravitational-wave signals from spinning neutron stars. V. A narrow-band all-sky search
An all-sky coherent search for periodic signals of gravitational waves in narrow-band data of a detector based on a statistic, commonly called the F-statistic, derived from the maximum-likelihood principle is presented.
Searches for continuous gravitational waves from nine young supernova remnants
We describe directed searches for continuous gravitational waves in data from the sixth LIGO science data run. The targets were nine young supernova remnants not associated with pulsars; eight of the
