@article{Abbott2009EinsteinHomeSF, title={Einstein@Home search for periodic gravitational waves in LIGO S4 data}, author={Ligo Scientific Collaboration B. Abbott and et al.}, journal={Physical Review D}, year={2009}, volume={79}, pages={022001} }
A search for periodic gravitational waves, from sources such as isolated rapidly spinning neutron stars, was carried out using 510 h of data from the fourth LIGO science run (S4). The search was for quasimonochromatic waves in the frequency range from 50 to 1500 Hz, with a linear frequency drift f˙ (measured at the solar system barycenter) in the range -f/τ<f˙<0.1f/τ, where the minimum spin-down age τ was 1000 yr for signals below 300 Hz and 10 000 yr above 300 Hz. The main computational work…
