Investigation and mitigation of noise contributions in a compact heterodyne interferometer
Yanqi Zhang, Adam Hines, Guillermo Valdes +1
We present a noise estimation and subtraction algorithm capable of increasing the sensitivity of heterodyne laser interferometers by one order of magnitude. The heterodyne interfer…
Optomechanical accelerometers for geodesy
Adam Hines, Andrea Nelson, Yanqi Zhang +4
We present a novel optomechanical inertial sensor for low frequency applications and corresponding acceleration measurements. This sensor has a resonant frequency of 4.7Hz, a mecha…
Daily monitoring of scattered light noise due to microseismic variability at the Virgo interferometer
Alessandro Longo, Stefano Bianchi, Guillermo Valdes +2
Data acquired by the Virgo interferometer during the second part of the O3 scientific run, referred to as O3b, were analysed with the aim of characterising the onset and time evolu…
Point Absorber Limits to Future Gravitational-Wave Detectors
W. Jia, H. Yamamoto, K. Kuns +198
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors…
Gwadaptive_scattering: an automated pipeline for scattered light noise characterization
Stefano Bianchi, Alessandro Longo, Guillermo Valdes +2
Scattered light noise affects the sensitivity of gravitational waves detectors. The characterization of such noise is needed to mitigate it. The time-varying filter empirical mode…
LIGOs Quantum Response to Squeezed States
L. McCuller, S. E. Dwyer, A. C. Green +194
Gravitational Wave interferometers achieve their profound sensitivity by combining a Michelson interferometer with optical cavities, suspended masses, and now, squeezed quantum sta…
Approaching the motional ground state of a 10 kg object
Chris Whittle, Evan D. Hall, Sheila Dwyer +197
The motion of a mechanical object -- even a human-sized object -- should be governed by the rules of quantum mechanics. Coaxing them into a quantum state is, however, difficult: th…
A search for a 5th planet around HR 8799 using the star-hopping RDI technique at VLT/SPHERE
Z. Wahhaj, J. Milli, C. Romero +8
The direct imaging of extrasolar giant planets demands the highest possible contrasts (dH ~10 magnitudes) at the smallest angular separations (~0.1'') from the star. We present an…
LIGO Detector Characterization in the Second and Third Observing Runs
D. Davis, J. S. Areeda, B. K. Berger +284
The characterization of the Advanced LIGO detectors in the second and third observing runs has increased the sensitivity of the instruments, allowing for a higher number of detecta…
Environmental Noise in Advanced LIGO Detectors

The sensitivity of the Advanced LIGO detectors to gravitational waves can be affected by environmental disturbances external to the detectors themselves. Since the transition from…
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…
