# Fully coherent follow-up of continuous gravitational-wave candidates: an application to Einstein@Home results

@article{Shaltev2014FullyCF, title={Fully coherent follow-up of continuous gravitational-wave candidates: an application to Einstein@Home results}, author={Miroslav Shaltev and Paola Leaci and Maria Alessandra Papa and Reinhard Prix}, journal={Physical Review D}, year={2014}, volume={89}, pages={124030} }

We characterize and present the details of the follow-up method used on the most significant outliers of the Hough Einstein@Home all-sky search for continuous gravitational waves [J. Aasi et al Phys. Rev. D 87, 042001 (2013)]. This follow-up method is based on the two-stage approach introduced by [M. Shaltev and R. Prix, Phys. Rev. D 87, 084057 (2013)], consisting of a semicoherent refinement followed by a fully coherent zoom. We quantify the efficiency of the follow-up pipeline using simulated…

This paper considers directed searches, i.e., targets for which the sky position is known accurately but the frequency and spin-down parameters are completely unknown, and presents a general framework that allows us to solve all three of these problems.

It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
