Point absorbers in Advanced LIGO
Aidan F. Brooks, Gabriele Vajente, Hiro Yamamoto +198
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations a…
Advanced LIGO Two-Stage Twelve-Axis Vibration Isolation and Positioning Platform. Part 2: Experimental Investigation and Tests Results
Fabrice Matichard, Brian Lantz, Kenneth Mason +37
This paper presents the results of the past seven years of experimental investigation and testing done on the two-stage twelve-axis vibration isolation platform for Advanced LIGO g…
Ground motion prediction at gravitational wave observatories using archival seismic data
Nikhil Mukund, Michael Coughlin, Jan Harms +13
Gravitational wave observatories have always been affected by tele-seismic earthquakes leading to a decrease in duty cycle and coincident observation time. In this analysis, we lev…
Advanced LIGO Two-Stage Twelve-Axis Vibration Isolation and Positioning Platform. Part 1: Design and Production Overview
Fabrice Matichard, Brian Lantz, Kenneth Mason +37
New generations of gravity wave detectors require unprecedented levels of vibration isolation. This paper presents the final design of the vibration isolation and positioning platf…
The US Program in Ground-Based Gravitational Wave Science: Contribution from the LIGO Laboratory
David Reitze, Rich Abbott, Carl Adams +181
Recent gravitational-wave observations from the LIGO and Virgo observatories have brought a sense of great excitement to scientists and citizens the world over. Since September 201…
Limiting the effects of earthquakes on gravitational-wave interferometers
Michael Coughlin, Paul Earle, Jan Harms +9
Ground-based gravitational wave interferometers such as the Laser Interferometer Gravitational-wave Observatory (LIGO) are susceptible to high-magnitude teleseismic events, which c…
