Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1245
Advanced LIGO and Advanced Virgo are actively monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this pape…
Black Hole Ringdown as a Probe for Dark Energy
Johannes Noller, Luca Santoni, Enrico Trincherini +1
Under the assumption that a dynamical scalar field is responsible for the current acceleration of the Universe, we explore the possibility of probing its physics in black hole merg…
Generalized covariant prescriptions for averaging cosmological observables
Giuseppe Fanizza, Maurizio Gasperini, Giovanni Marozzi +1
We present two new covariant and general prescriptions for averaging scalar observables on spatial regions typical of the observed sources and intersecting the past light-cone of a…
Fractal geometry of higher derivative gravity
Maximilian Becker, Carlo Pagani, Omar Zanusso
We determine the scaling properties of geometric operators such as lengths, areas, and volumes in models of higher derivative quantum gravity by renormalizing appropriate composite…
Energy-momentum tensor and helicity for gauge fields coupled to a pseudo-scalar inflaton
M. Ballardini, M. Braglia, F. Finelli +2
We study the energy-momentum tensor and helicity of gauge fields coupled through to a pseudo-scalar field driving inflation. Under the assumption of a consta…
Astrodynamical middle-frequency interferometric gravitational wave observatory AMIGO: Mission concept and orbit design
Wei-Tou Ni, Gang Wang, An-Ming Wu
AMIGO is a first-generation Astrodynamical Middle-frequency Interferometric GW Observatory. The scientific goals of AMIGO are: to bridge the spectra gap between first-generation hi…
Fakeons and microcausality: light cones, gravitational waves and the Hubble constant
Damiano Anselmi, Antonio Marino
The concept of fake particle, or "fakeon", allows us to make sense of quantum gravity as an ultraviolet complete theory, by renouncing causality at very small distances. We investi…
Constraints on the binary black hole nature of GW151226 and GW170608 from the measurement of spin-induced quadrupole moments
N. V. Krishnendu, M. Saleem, A. Samajdar +3
According to the "no-hair" conjecture, a Kerr black hole (BH) is completely described by its mass and spin. In particular, the spin-induced quadrupole moment of a Kerr BH with mass…
Model comparison from LIGO-Virgo data on GW170817's binary components and consequences for the merger remnant
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1191
GW170817 is the very first observation of gravitational waves originating from the coalescence of two compact objects in the mass range of neutron stars, accompanied by electromagn…
AEDGE: Atomic Experiment for Dark Matter and Gravity Exploration in Space
Yousef Abou El-Neaj, Cristiano Alpigiani, Sana Amairi-Pyka +129
We propose in this White Paper a concept for a space experiment using cold atoms to search for ultra-light dark matter, and to detect gravitational waves in the frequency range bet…
Search for intermediate mass black hole binaries in the first and second observing runs of the Advanced LIGO and Virgo network
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1196
Gravitational wave astronomy has been firmly established with the detection of gravitational waves from the merger of ten stellar mass binary black holes and a neutron star binary.…
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…
Analysis of ring laser gyroscopes including laser dynamics
Angela D. V. Di Virgilio, Nicolò Beverini, Giorgio Carelli +3
Inertial sensors stimulate very large interest, not only for their application but also for fundamental physics tests. Ring laser gyros, which measure angular rotation rate, are ce…
Cosmological constant: relaxation vs multiverse
Alessandro Strumia, Daniele Teresi
We consider a scalar field with a bottom-less potential, such as , finding that cosmologies unavoidably end up with a crunch, late enough to be compatible with observations…
Inspiral-Merger-Ringdown Consistency Tests with Higher Modes on Gravitational Signals from the Second Observing Run of LIGO and Virgo
Matteo Breschi, Richard O'Shaughnessy, Jacob Lange +1
Current tests of General Relativity are performed using approximations which neglect a key feature of complete solution of Einstein's theory: higher-order modes. Our analysis will…
All-sky search for long-duration gravitational-wave transients in the second Advanced LIGO observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1183
We present the results of a search for long-duration gravitational-wave transients in the data from the Advanced LIGO second observation run; we search for gravitational-wave trans…
Directional limits on persistent gravitational waves using data from Advanced LIGO's first two observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1132
We perform an unmodeled search for persistent, directional gravitational wave (GW) sources using data from the first and second observing runs of Advanced LIGO. We do not find evid…

Katerina Chatziioannou, Roberto Cotesta, Sudarshan Ghonge +53
We present a detailed investigation into the properties of GW170729, the gravitational wave with the most massive and distant source confirmed to date. We employ an extensive set o…
Search for the isotropic stochastic background using data from Advanced LIGO's second observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1133
The stochastic gravitational-wave background is a superposition of sources that are either too weak or too numerous to detect individually. In this study we present the results fro…
Narrow-band search for gravitational waves from known pulsars using the second LIGO observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1135
Isolated spinning neutron stars, asymmetric with respect to their rotation axis, are expected to be sources of continuous gravitational waves. The most sensitive searches for these…

Fakeons and the classicization of quantum gravity: the FLRW metric
Damiano Anselmi
Under certain assumptions, it is possible to make sense of higher derivative theories by quantizing the unwanted degrees of freedom as fakeons, which are later projected away. Then…
