@article{Ming2022ResultsFA, title={Results From an Einstein@Home Search for Continuous Gravitational Waves From G347.3 at Low Frequencies in LIGO O2 Data}, author={Jin Ming and Maria Alessandra Papa and H. B. Eggenstein and B. Machenschalk and B. Steltner and Reinhard Prix and Bruce Allen and O. Behnke}, journal={The Astrophysical Journal}, year={2022}, volume={925} }

We present results of a search for periodic gravitational wave signals with frequencies between 20 and 400 Hz from the neutron star in the supernova remnant G347.3-0.5 using LIGO O2 public data. The search is deployed on the volunteer computing project Einstein@Home, with thousands of participants donating compute cycles to make this endeavour possible. We find no significant signal candidate and set the most constraining upper limits to date on the amplitude of gravitational wave signals from…

### Application of a hierarchical MCMC follow-up to Advanced LIGO continuous gravitational-wave candidates

- Computer SciencePhysical Review D

All but five outliers are inconsistent with an astrophysical origin under the standard continuous wave signal model, and four are ascribed to instrumental artifacts and a strong hardware injection present in the data.

### Empirically estimating the distribution of the loudest candidate from a gravitational-wave search

- Computer SciencePhysical Review D
- 2022

This work introduces a new approach using extreme value theory to describe the distribution of the loudest template’s detection statistic in an arbitrary template bank, which automatically generalizes to a wider class of detection statistics, and improves the estimation of the expected maximum detection statistic at a negligible computing cost.
