Report on an all-sky LIGO search for periodic gravitational waves in the S4 data

Abstract

Abstract. We report on an all-sky search with the LIGO detectors for periodic gravitational waves in the frequency range 50-1000 Hz and having a negative frequency time derivative with magnitude between zero and 10 −8 Hz/s. Data from the fourth LIGO science run have been used in this search. Three different semi-coherent methods of summing strain power were applied. Observing no evidence for periodic gravitational radiation, we report upper limits on strain amplitude and interpret these limits to constrain radiation from rotating neutron stars.

Gravitational Wave in the Theory with the Universal Charge

“…Gravitational radiation as Planck neutrinos does not generate quadrupole oscillations when passing through the detector. Non-detection of gravitational waves in the LIGO and other projects [4] may be considered as an indirect evidence for the approach proposed. It is reasonable to believe that Planck neutrino does not take part in electromagnetic and weak interactions and does in strong and gravitational interactions.…”

“…This is considered as an indirect evidence for the existence of the gravitational waves. However, the LIGO project and its international counterparts have not detected gravitational waves [4].…”
