Pulsars and Gravitational Wave Detection | George Hobbs
; | Date: |
7 Dec 2004 | Subject: | astro-ph | Abstract: | The number of known millisecond pulsars has dramatically increased in the last few years. Regular observations of these pulsars may allow gravitational waves with frequencies ~10^-9 Hz to be detected. A ``pulsar timing array’’ is therefore complimentary to other searches for gravitational waves using ground-based or space-based interferometers that are sensitive to much higher frequencies. In this review we describe 1) the basic methods for using an array of pulsars as a gravitational wave detector, 2) the sources of the potentially detectable waves, 3) current limits on individual sources and a stochastic background and 4) the new project recently started using the Parkes radio telescope. | Source: | arXiv, astro-ph/0412153 | Services: | Forum | Review | PDF | Favorites |
