A calculation of gravitational radiation

Nagata, Kenneth Wayne January 1980 (has links)
Approximate gravitational field equations in an alternative theory of gravity are solved for a class of boundary conditions. The generation of gravitational radiation from spatially bounded sources is analyzed, and it is found that the theory predicts the emission of dipole gravitational radiation. However, the dipole radiation vanishes for slow-motion post-Newtonian sources. / Science, Faculty of / Physics and Astronomy, Department of / Graduate

Search for Long-Duration Transient Gravitational Waves Associated with Magnetar Bursts during LIGO’s Sixth Science Run

Quitzow-James, Ryan 27 October 2016 (has links)
Soft gamma repeaters (SGRs) and anomalous X-ray pulsars are thought to be neutron stars with strong magnetic fields, called magnetars, which emit intermittent bursts of hard X-rays and soft gamma rays. Three highly energetic bursts, known as giant flares, have been observed originating from three different SGRs, the latest and most energetic of which occurred on December 27, 2004, from the SGR with the largest estimated magnetic field, SGR 1806-20. Modulations in the X-ray tails of giant flares may be caused by global seismic oscillations. Non-radial oscillations of the dense neutron star matter could emit gravitational waves powered by the magnetar's magnetic energy reservoir. This analysis searched for long-duration transient gravitational waves associated with three magnetar bursts that occurred during LIGO's sixth science run, from July 7, 2009 to October 20, 2010. The search results were consistent with the calculated background, and 90% confidence upper limits on the possible undetected gravitational wave energy were found.

Hartmann wavefront sensors for advanced gravitational wave interferometers.

Brooks, Aidan F. January 2007 (has links)
Title page, contents and abstract only. The complete thesis in print form is available from the University of Adelaide Library. / This thesis describes an interferometric validation of the analytic solution for the thermal gradient which is central to numerical modelling of advanced GvVI. The bulk of the thesis, however, concentrates on the development and testing of a wavefront sensor for wavefront compensation. It also describes a Hartmann wavefront sensor that can measure wavefront changes, such as those due to substrate and coating absorption in GvVL with unprecedented precision and accuracy. According to the author it is simple to optimize and reliable, and appears very suitable for measuring wavefront distortion in advanced gravitational wave interferometers. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1295719 / Thesis (Ph.D.) -- University of Adelaide, School of Chemistry and Physics, 2007
