Virgo Detector Characterization and Data Quality: tools
F. Acernese, M. Agathos, A. Ain +491
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the jo…
Virgo Detector Characterization and Data Quality: results from the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Adv…
Virgo Detector Characterization and Data Quality during the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave signals in the past few years, alongside the two LIGO ins…
Bifurcation theory captures band formation in the Vicsek model of flock formation
C. Trenado, L. L. Bonilla, A. Marquina
Collective behavior occurs ubiquitously in nature and it plays a key role in bacterial colonies, mammalian cells or flocks of birds. Here, we examine the average density and veloci…
The Virgo O3 run and the impact of the environment
F. Acernese, M. Agathos, A. Ain +486
Sources of geophysical noise (such as wind, sea waves and earthquakes) or of anthropogenic noise impact ground-based gravitational-wave interferometric detectors, causing transient…
Implementation of the rROF denoising method in the cWB pipeline for gravitational-wave data analysis
Pablo J. Barneo, Alejandro Torres-Forné, José A. Font +3
The data collected by the current network of gravitational-wave detectors are largely dominated by instrumental noise. Total variation methods based on L1-norm minimization have re…
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…
Classification of gravitational-wave glitches via dictionary learning
Miquel Llorens-Monteagudo, Alejandro Torres-Forné, José A. Font +1
We present a new method for the classification of transient noise signals (or glitches) in advanced gravitational-wave interferometers. The method uses learned dictionaries (a supe…
A standard siren measurement of the Hubble constant from GW170817 without the electromagnetic counterpart
M. Fishbach, R. Gray, I. Magaña Hernandez +316
We perform a statistical standard siren analysis of GW170817. Our analysis does not utilize knowledge of NGC 4993 as the unique host galaxy of the optical counterpart to GW170817.…
Total-variation methods for gravitational-wave denoising: performance tests on Advanced LIGO data
Alejandro Torres-Forné, Elena Cuoco, Antonio Marquina +2
We assess total-variation methods to denoise gravitational-wave signals in real noise conditions, by injecting numerical-relativity waveforms from core-collapse supernovae and bina…
Neutron star collapse and gravitational waves with a non-convex equation of state
M. A. Aloy, J. M. Ibáñez, N. Sanchis-Gual +4
The thermodynamical properties of the equation of state (EoS) of high-density matter (above nuclear saturation density) and the possible existence of exotic states such as phase tr…
Denoising of gravitational wave signals via dictionary learning algorithms
Alejandro Torres-Forné, Antonio Marquina, José A. Font +1
Gravitational wave astronomy has become a reality after the historical detections accomplished during the first observing run of the two advanced LIGO detectors. In the following y…
Denoising of gravitational-wave signal GW150914 via total-variation methods
Alejandro Torres-Forné, Antonio Marquina, José A. Font +1
We apply a regularized Rudin-Osher-Fatemi total variation (TV) method to denoise the transient gravitational wave signal GW150914. We have previously applied TV techniques to denoi…
Wavelength selection of rippling patterns in myxobacteria
L. L. Bonilla, A. Glavan, A. Marquina
Rippling patterns of myxobacteria appear in starving colonies before they aggregate to form fruiting bodies. These periodic traveling cell density waves arise from the coordination…
Total-variation-based methods for gravitational wave denoising
Alejandro Torres, Antonio Marquina, José A. Font +1
We describe new methods for denoising and detection of gravitational waves embedded in additive Gaussian noise. The methods are based on Total Variation denoising algorithms. These…
