We present a novel Machine Learning (ML) based strategy to search for compact binary coalescences (CBCs) in data from ground-based gravitational wave (GW) observatories. This is the first ML-based search that not only recovers all the binary black hole mergers in the first GW transients calalog (GWTC-1), but also makes a clean detection of GW151216, which was not significant enough to be included in the catalogue. Moreover, we achieve this by only adding a new coincident ranking statistic…

Source-Agnostic Gravitational-Wave Detection with Recurrent Autoencoders
The recurrent autoencoder outperforms other autoencoders based on different architectures and could complement the search strategy employed for gravitational wave detection and extend the reach of the ongoing detection campaigns.


Deep Learning for Real-time Gravitational Wave Detection and Parameter Estimation: Results with Advanced LIGO Data
It is demonstrated for the first time that machine learning can detect and estimate the true parameters of real events observed by LIGO, and achieves similar sensitivities and lower errors compared to matched-filtering while being far more computationally efficient and more resilient to glitches.
2-OGC: Open Gravitational-wave Catalog of Binary Mergers from Analysis of Public Advanced LIGO and Virgo Data
We present the second Open Gravitational-wave Catalog (2-OGC) of compact-binary coalescences, obtained from the complete set of public data from Advanced LIGO's first and second observing runs. For

After their successful first observing run (September 12, 2015 - January 12, 2016), the Advanced LIGO detectors were upgraded to increase their sensitivity for the second observing run (November 30,
Distinguishing short duration noise transients in LIGO data to improve the PyCBC search for gravitational waves from high mass binary black hole mergers
"Blip glitches" are a type of short duration transient noise in LIGO data. The cause for the majority of these is currently unknown. Short duration transient noise creates challenges for searches of
Assessing gravitational-wave binary black hole candidates with Bayesian odds
Gravitational waves from the coalescence of binary black holes can be distinguished from noise transients in a detector network through Bayesian model selection by exploiting the coherence of the
Gravity Spy: integrating advanced LIGO detector characterization, machine learning, and citizen science.
An innovative project that combines crowdsourcing with machine learning to aid in the challenging task of categorizing all of the glitches recorded by the LIGO detectors is described and a combined method with the aim of improving the efficiency and accuracy of each individual classifier is created.
