On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long dedicated search for gravitational radiation. The LIGO detectors have achieved a higher duty cycle and greater sensitivity to gravitational waves than ever before, with LIGO Hanford achieving angle-averaged sensitivity to binary neutron star coalescences to a distance of 111 Mpc, and LIGO Livingston to 134 Mpc with duty… 

Review of the Advanced LIGO Gravitational Wave Observatories Leading to Observing Run Four

Gravitational waves from binary black hole and neutron star mergers are being regularly detected. As of 2021, 90 confident gravitational wave detections have been made by the LIGO and Virgo

Point absorbers in Advanced LIGO.

This analysis predicts that the power-dependent reduction in interferometer performance will significantly degrade maximum stored power by up to 50% and, hence, limit GW sensitivity, but it suggests system wide corrections that can be implemented in current and future GW detectors.

Quantum correlations between light and the kilogram-mass mirrors of LIGO

Quantum correlations between the laser beams and the positions of the 40-kg mirrors of LIGO are confirmed experimentally, enabling high-precision measurements of both gravitational waves and macroscopic quantum states.

Nonlinear Noise Cleaning in Gravitational-Wave Detectors With Convolutional Neural Networks

This study examines the requirements in the signal-to-noise ratio (SNR) in both the target channel and in the auxiliary sensors in order to reduce the noise by at least a factor of a few, and shows that the CNN can still reach a good performance if it is used in the case of limited SNR.

Ultimate limits and prospects of long-baseline optical fiber interferometry
