# Robust semicoherent searches for continuous gravitational waves with noise and signal models including hours to days long transients

@article{Keitel2016RobustSS, title={Robust semicoherent searches for continuous gravitational waves with noise and signal models including hours to days long transients}, author={David Keitel}, journal={Physical Review D}, year={2016}, volume={93}, pages={084024} }

The vulnerability to single-detector instrumental artifacts in standard detection methods for long-duration quasimonochromatic gravitational waves from nonaxisymmetric rotating neutron stars [continuous waves (CWs)] was addressed in past work [D. Keitel et al., Phys. Rev. D 89, 064023 (2014).] by a Bayesian approach. An explicit model of persistent single-detector disturbances led to a generalized detection statistic with improved robustness against such artifacts. Since many strong outliers in… Expand
