The Transient Gravitational-Wave Sky
Nils Andersson, John Baker, Kris Belczynski +44
Interferometric detectors will very soon give us an unprecedented view of the gravitational-wave sky, and in particular of the explosive and transient Universe. Now is the time to…
A search for gravitational waves associated with the August 2006 timing glitch of the Vela pulsar
The LIGO Scientific Collaboration, J. Abadie, B. P. Abbott +499
The physical mechanisms responsible for pulsar timing glitches are thought to excite quasi-normal mode oscillations in their parent neutron star that couple to gravitational wave e…
First search for gravitational waves from the youngest known neutron star
LIGO Scientific Collaboration, J. Abadie, B. P. Abbott +537
We present a search for periodic gravitational waves from the neutron star in the supernova remnant Cassiopeia A. The search coherently analyzes data in a 12-day interval taken fro…
Singular value decomposition applied to compact binary coalescence gravitational-wave signals
Kipp Cannon, Adrian Chapman, Chad Hanna +3
We investigate the application of the singular value decomposition to compact-binary, gravitational-wave data-analysis. We find that the truncated singular value decomposition redu…
X-Pipeline: An analysis package for autonomous gravitational-wave burst searches
Patrick J. Sutton, Gareth Jones, Shourov Chatterji +8
Autonomous gravitational-wave searches -- fully automated analyses of data that run without human intervention or assistance -- are desirable for a number of reasons. They are nece…
Bayesian detection of unmodeled bursts of gravitational waves
Antony C. Searle, Patrick J. Sutton, Massimo Tinto
The data analysis problem of coherently searching for unmodeled gravitational-wave bursts in the data generated by a global network of gravitational-wave observatories has been at…
First joint search for gravitational-wave bursts in LIGO and GEO600 data
LIGO Scientific Collaboration, B. Abbott
We present the results of the first joint search for gravitational-wave bursts by the LIGO and GEO600 detectors. We search for bursts with characteristic central frequencies in the…
Monte-Carlo and Bayesian techniques in gravitational wave burst data analysis
Antony C. Searle
Monte-Carlo simulations are used in the gravitational wave burst detection community to demonstrate and compare the properties of different search techniques. We note that every Mo…
Robust Bayesian detection of unmodelled bursts
Antony C Searle, Patrick J Sutton, Massimo Tinto +1
A Bayesian treatment of the problem of detecting an unmodelled gravitational wave burst with a global network of gravitational wave observatories reveals that several previously pr…
LIGO: The Laser Interferometer Gravitational-Wave Observatory
The LIGO Scientific Collaboration, B. Abbott
The goal of the Laser Interferometric Gravitational-Wave Observatory (LIGO) is to detect and study gravitational waves of astrophysical origin. Direct detection of gravitational wa…
Numerical wave optics and the lensing of gravitational waves by globular clusters
Andrew J. Moylan, David E. McClelland, Susan M. Scott +2
We consider the possible effects of gravitational lensing by globular clusters on gravitational waves from asymmetric neutron stars in our galaxy. In the lensing of gravitational w…
Functional programming framework for GRworkbench
Andrew J. Moylan, Susan M. Scott, Antony C. Searle
The software tool GRworkbench is an ongoing project in visual, numerical General Relativity at The Australian National University. Recently, the numerical differential geometric en…
Upper limits on gravitational wave emission from 78 radio pulsars
The LIGO Scientific Collaboration, B. Abbott, M. Kramer +1
We present upper limits on the gravitational wave emission from 78 radio pulsars based on data from the third and fourth science runs of the LIGO and GEO600 gravitational wave dete…
Coherent searches for periodic gravitational waves from unknown isolated sources and Scorpius X-1: results from the second LIGO science run
The LIGO Scientific Collaboration
We carry out two searches for periodic gravitational waves using the most sensitive few hours of data from the second LIGO science run. The first search is targeted at isolated, pr…
Coherent network analysis technique for discriminating gravitational-wave bursts from instrumental noise
Shourov Chatterji, Albert Lazzarini, Leo Stein +3
Existing coherent network analysis techniques for detecting gravitational-wave bursts simultaneously test data from multiple observatories for consistency with the expected propert…
Developments in GRworkbench
A. Moylan, S. M. Scott, A. C. Searle
The software tool GRworkbench is an ongoing project in visual, numerical General Relativity at The Australian National University. Recently, GRworkbench has been significantly exte…
The ACIGA Data Analysis programme
Susan M Scott, Antony C Searle, Benedict J Cusack +1
The Data Analysis programme of the Australian Consortium for Interferometric Gravitational Astronomy (ACIGA) was set up in 1998 by the first author to complement the then existing…
Spectral Line Removal in the LIGO Data Analysis System (LDAS)
Antony C. Searle, Susan M. Scott, David E. McClelland
High power in narrow frequency bands, spectral lines, are a feature of an interferometric gravitational wave detector's output. Some lines are coherent between interferometers, in…
GRworkbench: A Computational System Based on Differential Geometry
Susan M Scott, Benjamin J K Evans, Antony C Searle
We have developed a new tool for numerical work in General Relativity: GRworkbench. While past tools have been ad hoc, GRworkbench closely follows the framework of Differential Geo…
Network sensitivity to geographical configuration
Antony C Searle, Susan M Scott, David E McClelland
Gravitational wave astronomy will require the coordinated analysis of data from the global network of gravitational wave observatories. Questions of how to optimally configure the…
