Reducing the impact of seismic activity on the motion of suspended optics is essential for the operation of ground-based gravitational wave detectors. During periods of increased seismic activity, low-frequency ground translation and tilt cause the Advanced LIGO observatories to lose `lock', reducing their duty cycles. This paper applies modern global-optimisation algorithms to aid in the design of the `sensor correction' filter, used in the control of the active platforms. It is shown that a… Expand

GWTC-1: A Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs
We present the results from three gravitational-wave searches for coalescing compact binaries with component masses above 1$\mathrm{M}_\odot$ during the first and second observing runs of theExpand
Subtracting Tilt from a Horizontal Seismometer Using a Ground‐Rotation Sensor
Abstract We demonstrate the use of a high‐precision ground‐rotation sensor to subtract wind‐induced tilt noise in a horizontal broadband seismometer at frequencies above 10 mHz. The measurement wasExpand

GW150914: The Advanced LIGO Detectors in the Era of First Discoveries.
TLDR
Following a major upgrade, the two advanced detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO) held their first observation run between September 2015 and January 2016, and observed a transient gravitational-wave signal determined to be the coalescence of two black holes.
