Accurate calibration of test mass displacement in the LIGO interferometers
E. Goetz, R. L. Savage, J. Garofoli +10
We describe three fundamentally different methods we have applied to calibrate the test mass displacement actuators to search for systematic errors in the calibration of the LIGO g…
An Upper Limit on the Stochastic Gravitational-Wave Background of Cosmological Origin
The LIGO Scientific Collaboration, the Virgo Collaboration
A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources of astrophysical and cosmologica…
Precise calibration of LIGO test mass actuators using photon radiation pressure
E. Goetz, P. Kalmus, S. Erickson +9
Precise calibration of kilometer-scale interferometric gravitational wave detectors is crucial for source localization and waveform reconstruction. A technique that uses the radiat…
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…
Stacking Gravitational Wave Signals from Soft Gamma Repeater Bursts
P. Kalmus, K. C. Cannon, S. Marka +1
Soft gamma repeaters (SGRs) have unique properties that make them intriguing targets for gravitational wave (GW) searches. They are nearby, their burst emission mechanism may invol…
Search for Gravitational Wave Bursts from Soft Gamma Repeaters
Peter Kalmus
We present the results of a LIGO search for short-duration gravitational waves (GW) associated with soft gamma repeater (SGR) bursts. This is the first GW search sensitive to neutr…
