Convolutional Neural Networks for the classification of glitches in gravitational-wave data streams
Tiago S. Fernandes, Samuel J. Vieira, Antonio Onofre +3
We investigate the use of Convolutional Neural Networks (including the modern ConvNeXt network family) to classify transient noise signals (i.e.~glitches) and gravitational waves i…
Solving the Teukolsky equation with physics-informed neural networks
Raimon Luna, Juan Calderón Bustillo, Juan José Seoane Martínez +2
We use physics-informed neural networks (PINNs) to compute the first quasi-normal modes of the Kerr geometry via the Teukolsky equation. This technique allows us to extract the com…
Dictionary learning: a novel approach to detecting binary black holes in the presence of Galactic noise with LISA
Charles Badger, Katarina Martinovic, Alejandro Torres-Forné +2
The noise produced by the inspiral of millions of white dwarf binaries in the Milky Way may pose a threat to one of the main goals of the space-based LISA mission: the detection of…
Searching for vector boson-star mergers within LIGO-Virgo intermediate-mass black-hole merger candidates
Juan Calderon Bustillo, Nicolas Sanchis-Gual, Samson H. W. Leong +7
We present the first systematic search for exotic compact mergers in Advanced LIGO and Virgo events. We compare the short gravitational-wave signals GW190521, GW190426190642, G…
Gravitational-wave parameter inference with the Newman-Penrose scalar
Juan Calderon Bustillo, Isaac C. F. Wong, Nicolas Sanchis-Gual +7
Detection and parameter inference of gravitational-wave signals \ncor{from compact mergers} rely on the comparison of the incoming detector strain data to waveform templates…
Inference of proto-neutron star properties from gravitational-wave data in core-collapse supernovae
Marie-Anne Bizouard, Patricio Maturana-Russel, Alejandro Torres-Forné +5
The eventual detection of gravitational waves from core-collapse supernovae (CCSN) will help improve our current understanding of the explosion mechanism of massive stars. The stoc…
Exploring gravitational-wave detection and parameter inference using Deep Learning methods
João D. Álvares, José A. Font, Felipe F. Freitas +5
We explore machine learning methods to detect gravitational waves (GW) from binary black hole (BBH) mergers using deep learning (DL) algorithms. The DL networks are trained with gr…
Confusing Head-On Collisions with Precessing Intermediate-Mass Binary Black Hole Mergers
Juan Calderón Bustillo, Nicolas Sanchis-Gual, Alejandro Torres-Forné +1
We report a degeneracy between the gravitational-wave signals from quasi-circular precessing black-hole mergers and those from extremely eccentric mergers, namely head-on collision…
Application of dictionary learning to denoise LIGO's blip noise transients
Alejandro Torres-Forné, Elena Cuoco, José A. Font +1
Data streams of gravitational-wave detectors are polluted by transient noise features, or "glitches", of instrumental and environmental origin. In this work, we investigate the use…
All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1186
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gra…
Universal relations for gravitational-wave asteroseismology of proto-neutron stars
Alejandro Torres-Forné, Pablo Cerdá-Durán, Martin Obergaulinger +2
State-of-the-art numerical simulations of core-collapse supernovae reveal that the main source of gravitational waves is the excitation of proto-neutron star modes during post-boun…
Calibration of Advanced Virgo and Reconstruction of the Gravitational Wave Signal h(t) during the Observing Run O2
Virgo Collaboration, F. Acernese, T. Adams +281
In August 2017, Advanced Virgo joined Advanced LIGO for the end of the O2 run, leading to the first gravitational waves detections with the three-detector network. This paper descr…
Black holes, gravitational waves and fundamental physics: a roadmap
Leor Barack, Vitor Cardoso, Samaya Nissanke +203
The grand challenges of contemporary fundamental physics---dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-…
