Phys. Rev. Lett. 83, 1498–1501 (1999)Observational Limit on Gravitational Waves from Binary Neutron Stars in the Galaxy
Using optimal matched filtering, we search 25 hours of data from the LIGO 40-m prototype laser interferometric gravitational-wave detector for gravitational-wave chirps emitted by coalescing binary systems within our Galaxy. This is the first test of this filtering technique on real interferometric data. An upper limit on the rate R of neutron star binary inspirals in our Galaxy is obtained: with 90% confidence, R<0.5h-1. Similar experiments with LIGO interferometers will provide constraints on the population of tight binary neutron star systems in the Universe. © 1999 The American Physical Society URL:
