High-precision Absolute Coordinate Measurement using Frequency Scanned Interferometry
Tianxiang Chen, Haijun Yang, Keith Riles +1
In this paper, we report high-precision absolute position measurement performed with frequency scanned interferometry (FSI). We reported previously on measurement of absolute dista…
Searches for continuous gravitational waves from Scorpius X-1 and XTE J1751-305 in LIGO's sixth science run
Grant David Meadors, Evan Goetz, Keith Riles +2
Scorpius X-1 (Sco X-1) and X-ray transient (XTE) J1751-305 are Low-Mass X-ray Binaries (LMXBs) that may emit continuous gravitational waves detectable in the band of ground-based i…
Tuning into Scorpius X-1: adapting a continuous gravitational-wave search for a known binary system
Grant David Meadors, Evan Goetz, Keith Riles
We describe how the TwoSpect data analysis method for continuous gravitational waves (GWs) has been tuned for directed sources such as the Low Mass X-ray Binary (LMXB), Scorpius X-…
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…
Searching for Dark Photon Dark Matter in LIGO O1 Data
Huai-Ke Guo, Keith Riles, Feng-Wei Yang +1
Dark matter exists in our Universe, but its nature remains mysterious. The remarkable sensitivity of the Laser Interferometer Gravitational-Wave Observatory (LIGO) may be able to s…
High-precision Absolute Distance Measurement using Dual-Laser Frequency Scanned Interferometry Under Realistic Conditions
Hai-Jun Yang, Keith Riles
In this paper, we report on new high-precision absolute distance measurements performed with frequency scanned interferometry using a pair of single-mode optical fibers. Absolute d…
