Detecting massive scalar fields with Extreme Mass-Ratio Inspirals
Susanna Barsanti, Andrea Maselli, Thomas P. Sotiriou +1
We study the imprint of light scalar fields on gravitational waves from extreme mass ratio inspirals -- binary systems with a very large mass asymmetry. We first show that, to lead…
Improved detection statistics for non Gaussian gravitational wave stochastic backgrounds
Matteo Ballelli, Riccardo Buscicchio, Barbara Patricelli +2
In a recent paper we described a novel approach to the detection and parameter estimation of a non-Gaussian stochastic background of gravitational waves. In this work we propose an…
Transverse Doppler effect and parameter estimation of LISA three-body systems
Adrien Kuntz, Konstantin Leyde
Some binary black hole systems potentially observable in LISA could be in orbit around a supermassive black hole (SMBH). The imprint of relativistic three-body effects on the wavef…
Disks, spikes, and clouds: distinguishing environmental effects on BBH gravitational waveforms
Philippa S. Cole, Gianfranco Bertone, Adam Coogan +5
Future gravitational wave interferometers such as LISA, Taiji, DECIGO, and TianQin, will enable precision studies of the environment surrounding black holes. In this paper, we stud…
gravity in the Jordan Frame as a Paradigm for the Hubble Tension
Tiziano Schiavone, Giovanni Montani, Flavio Bombacigno
We analyse the gravity in the so-called Jordan frame, as implemented to the isotropic Universe dynamics. The goal of the present study is to show that, according to recent d…
Effective two-body approach to the hierarchical three-body problem: quadrupole to 1PN
Adrien Kuntz, Francesco Serra, Enrico Trincherini
Many binary systems of interest for gravitational-wave astronomy are orbited by a third distant body, which can considerably alter their relativistic dynamics. Precision computatio…
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…
An analytic approach to quasinormal modes for coupled linear systems
Lam Hui, Alessandro Podo, Luca Santoni +1
Quasinormal modes describe the ringdown of compact objects deformed by small perturbations. In generic theories of gravity that extend General Relativity, the linearized dynamics o…
GINGER
Carlo Altucci, Francesco Bajardi Emilio Barchiesi, Andrea Basti +29
In this paper, we outline the scientific objectives, the experimental layout, and the collaborations envisaged for the GINGER (Gyroscopes IN GEneral Relativity) project. The GINGER…
Detecting non-Gaussian gravitational wave backgrounds: a unified framework
Riccardo Buscicchio, Anirban Ain, Matteo Ballelli +2
We describe a novel approach to the detection and parameter estimation of a non\textendash Gaussian stochastic background of gravitational waves. The method is based on the determi…
Black hole superradiance with (dark) matter accretion
Lam Hui, Y. T. Albert Law, Luca Santoni +3
Studies of black hole superradiance often focus on the growth of a cloud in isolation, accompanied by the spin-down of the black hole. In this paper, we consider the additional eff…
Quasi-normal modes of rotating black holes in Einstein-dilaton Gauss-Bonnet gravity: the second order in rotation
Lorenzo Pierini, Leonardo Gualtieri
One of the most promising strategies to test gravity in the strong-field, large curvature regime is gravitational spectroscopy: the measurement of black hole quasi-normal modes fro…
Cosmology in the dark: How compact binaries formation impact the gravitational-waves cosmological measurements
S. Mastrogiovanni, K. Leyde, C. Karathanasis +7
Information about the mass spectrum of compact stars can be used to infer cosmological parameters from gravitational waves (GW) in the absence of redshift measurements obtained fro…
Local solutions of General Relativity in the presence of the Trace Anomaly
Marco Calzá, Alessandro Casalino, Lorenzo Sebastiani
Local solutions are a vivid and long-living topic in gravitational physics. We consider exact static pseudo-spherically symmetric solutions of semi-classical Einstein's equations i…
Extreme mass-ratio inspirals as probes of scalar fields: eccentric equatorial orbits around Kerr black holes
Susanna Barsanti, Nicola Franchini, Leonardo Gualtieri +2
We study binary systems in which a stellar mass compact object spirals into a massive black hole, known as extreme mass ratio inspirals, in scenarios with a new fundamental scalar…
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…
First joint observation by the underground gravitational-wave detector, KAGRA, with GEO600
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1669
We report the results of the first joint observation of the KAGRA detector with GEO600. KAGRA is a cryogenic and underground gravitational-wave detector consisting of a laser inter…
Dissipative processes at the acoustic horizon
Maria Luisa Chiofalo, Dario Grasso, Massimo Mannarelli +1
A transonic fluid flow generates an acoustic hole that is the hydrodynamic analogue of a gravitational black hole. Acoustic holes emit a detectable thermal radiation of phonons at…

Results are presented for a semi-coherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using a hidden Markov model (HMM) to allow for spin…
Precession resonances in hierarchical triple systems
Adrien Kuntz
We describe a new kind of resonance occuring in relativistic three-body hierarchical systems: the precession resonance, occuring when the relativistic precession timescale of a bin…

Analysis of Ringdown Overtones in GW150914
Roberto Cotesta, Gregorio Carullo, Emanuele Berti +1
We analyze GW150914 post-merger data to understand if ringdown overtone detection claims are robust. We find no evidence in favor of an overtone in the data after the waveform peak…
