متن کاملApplication of a Hough search for continuous gravitational waves on data from the fifth LIGO science run
We report on an all-sky search for periodic gravitational waves in the frequency range 50–1000 Hz with the first derivative of frequency in the range −8.9 × 10−10 Hz s−1 to zero in two years of data collected during LIGO’s fifth science run. Our results employ a Hough transform technique, introducing a χ2 test and analysis of coincidences between the signal levels in years 1 and 2 of observatio...

We report on an all–sky search for periodic gravitational waves in the frequency range 50− 1000 Hz with the first derivative of frequency in the range −8.9 × 10−10 Hz/s to zero in two years of data collected during LIGO’s fifth science run. Our results employ a Hough transform technique, introducing a χ2 test and analysis of coincidences between the signal levels in years 1 and 2 of observation...
متن کاملThe Search for Gravitational Waves
The basic physics of g.w.'s emission, propagation and detection is outlined. The general features of candidate sources and detectors are discussed, showing how astrophysical emission events could be detected by devices not far from their Standard Quantum Limit. Two kinds of ground based detectors currently under active development, Km size interferometers and mK cold massive mechanical resonato...
