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 detectable gravitational-wave signals, and provided confirmation of all observed gravitational-wave events. In this work, we present the methods used to characterize the LIGO detectors and curate the publicly available datasets, including the LIGO strain data and data quality products. We describe the essential role of these… 
UniMAP: model-free detection of unclassified noise transients in LIGO-Virgo data using the temporal outlier factor
It is shown this windowing scheme extends the anomaly detection capabilities of the TOF algorithm to resolve noise transients of arbitrary morphology and duration to demonstrate the efficacy of this pipeline in detecting glitches during LIGO and Virgo’s third observing run.

We report on gravitational wave discoveries from compact binary coalescences detected by Advanced LIGO and Advanced Virgo between 1 April 2019 15:00 UTC and 1 October 2019 15:00. By imposing a
Narrowband Searches for Continuous and Long-duration Transient Gravitational Waves from Known Pulsars in the LIGO-Virgo Third Observing Run
Isolated neutron stars that are asymmetric with respect to their spin axis are possible sources of detectable continuous gravitational waves. This paper presents a fully coherent search for such
Hardware-accelerated inference for real-time gravitational-wave astronomy
This work reports a novel implementation and deployment of deep learning inference for real-time gravitational-wave data denoising and astrophysical source identification using a generic Inference-as-a-Service model that is capable of adapting to the future needs of gravitational- wave data analysis.
Search for intermediate-mass black hole binaries in the third observing run of Advanced LIGO and Advanced Virgo
Intermediate-mass black holes (IMBHs) span the approximate mass range 100 − 10 5 M (cid:12) , between black holes (BHs) that formed by stellar collapse and the supermassive BHs at the centers of
Search for Lensing Signatures in the Gravitational-Wave Observations from the First Half of LIGO–Virgo’s Third Observing Run
We search for signatures of gravitational lensing in the gravitational-wave signals from compact binary coalescences detected by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)

Dancing in the dark: detecting a population of distant primordial black holes
. Primordial black holes (PBHs) are compact objects proposed to have formed in the early Universe from the collapse of small-scale over-densities. Their existence may be detected from the observation
Utilizing the null stream of the Einstein Telescope
Among third-generation ground-based gravitational-wave detectors proposed for the next decade, Einstein Telescope provides a unique kind of null stream – the signal-free linear combination of data –

Upper limits on the isotropic gravitational-wave background from Advanced LIGO and Advanced Virgo’s third observing run
We report results of a search for an isotropic gravitational-wave background (GWB) using data from Advanced LIGO’s and Advanced Virgo’s third observing run (O3) combined with upper limits from the
Optimizing Advanced Ligo's Scientific Output with Fast, Accurate, Clean Calibration
Methods used in low and high latency to produce Advanced LIGO’s calibrated strain data are discussed, highlighting improvements to accuracy, latency, and noise reduction that have been made since the beginning of the second observing run (O2).
Virgo is a very independent zodiac sign. They are fully able to put their intelligence to use and get things done for themselves. It is possible however that their narrow mindedness causes their
