In this paper we present a hierarchical data analysis pipeline for all-sky searches of continuous gravitational wave signals, like those emitted by spinning neutron stars asymmetric with respect to the rotation axis, with unknown position, rotational frequency and spin-down. The core of the pipeline is an incoherent step based on a particularly efficient implementation of the Hough transform, that we call frequency-Hough, that maps the data time-frequency plane to the source frequency/spin-down… 

Method to search for long duration gravitational wave transients from isolated neutron stars using the generalized frequency-Hough transform

We describe a method to detect gravitational waves lasting $O(hours-days)$ emitted by young, isolated neutron stars, such as those that could form after a supernova or a binary neutron star merger,

An analysis of the FrequencyHough method for an all-sky search for continuous gravitational waves

In this paper we present an analysis of the Rome group’s pipeline for their all-sky search for continuous gravitational waves (CW) emitted by asymmetrically rotating neutron stars. We determine how

First low frequency all-sky search for continuous gravitational wave signals

In this paper we present the results of the first low frequency all-sky search of continuous gravitational wave signals conducted on Virgo VSR2 and VSR4 data. The search covered the full sky, a

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

We describe a method to detect gravitational waves lasting O ( hours − days ) emitted by young, isolated neutron stars, such as those that could form after a supernova or a binary neutron star

Time-frequency track distance for comparing continuous gravitational wave signals

Searches for continuous gravitational waves from unknown sources attempt to detect long-lasting gravitational radiation by identifying Doppler-modulated signatures in the data. Semicoherent methods

Phase decomposition of the template metric for continuous gravitational-wave searches

TLDR
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.

A Fast Data Processing Technique for Continuous Gravitational Wave Searches

TLDR
The potential advantages of a data processing technique for continuous gravitational wave signals searches in the data measured by ground-based gravitational wave interferometers, which is applied to a data set obtained by multiplying the original time-series with a (half-year) time-shifted copy of it.

An improved algorithm for narrow-band searches of continuous gravitational waves

Continuous gravitational waves signals, emitted by asymmetric spinning neutron stars, are among the main targets of current detectors like Advanced LIGO and Virgo. In the case of sources, like

Comparison of methods for the detection of gravitational waves from unknown neutron stars

Rapidly rotating neutron stars are promising sources of continuous gravitational wave radiation for the LIGO and Virgo interferometers. The majority of neutron stars in our galaxy have not been
