Fully coherent searches (over realistic ranges of parameter space and year-long observation times) for unknown sources of continuous gravitational waves are computationally prohibitive. Less expensive hierarchical searches divide the data into shorter segments which are analyzed coherently, then detection statistics from different segments are combined incoherently. The novel method presented here solves the long-standing problem of how best to do the incoherent combination. The optimal…

Parameter-space metric of semicoherent searches for continuous gravitational waves
Continuous gravitational-wave (CW) signals such as emitted by spinning neutron stars are an important target class for current detectors. However, the enormous computational demand prohibits fully
Weave: a semicoherent search implementation for continuous gravitational waves
TLDR
A new implementation of a semicoherent search method is presented that for the first time makes full use of a parameter-space metric to generate search templates in the correct resolution, combined with optimal lattices to minimize the required number of templates and hence the computational cost of the search.
Estimating the sensitivity of wide-parameter-space searches for gravitational-wave pulsars
This paper presents an in-depth study of how to estimate the sensitivity of searches for gravitational-wave pulsars -- rapidly-rotating neutron stars which emit quasi-sinusoidal gravitational waves.
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
Hierarchical multistage MCMC follow-up of continuous gravitational wave candidates
Leveraging Markov chain Monte Carlo (MCMC) optimization of the F-statistic, we introduce a method for the hierarchical follow-up of continuous gravitational wave candidates identified by
Fast and accurate sensitivity estimation for continuous-gravitational-wave searches
This paper presents an efficient numerical sensitivity-estimation method and implementation for continuous-gravitational-wave searches, extending and generalizing an earlier analytic approach by
Parameter-space metric for all-sky semicoherent searches for gravitational-wave pulsars
The sensitivity of all-sky searches for gravitational-wave pulsars is primarily limited by the finite availability of computing resources. Semicoherent searches are a widely-used method of maximizing
Implementation of barycentric resampling for continuous wave searches in gravitational wave data
TLDR
An efficient implementation of a coherent statistic for searches of continuous gravitational wave from neutron stars by transforming the data taken by a gravitational wave detector from a moving Earth bound frame to one that sits at the Solar System barycenter is described.
Implementing a semicoherent search for continuous gravitational waves using optimally constructed template banks
TLDR
A new implementation of a semicoherent search method is presented that for the first time makes full use of a parameter-space metric to generate banks of search templates at the correct resolution, combined with optimal lattices to minimize the required number of templates and hence the computational cost of the search.
Status and perspectives of Continuous Gravitational Wave searches
The birth of gravitational wave astronomy has been triggered by the detection of the first signal produced by the merger of two compact objects. The following discoveries by the Earth-based network
