Eikonal quasinormal modes of black holes beyond general relativity II: generalised scalar-tensor perturbations
Hector O. Silva, Kostas Glampedakis
Black hole `spectroscopy', i.e. the identification of quasinormal mode frequencies via gravitational wave observations, is a powerful technique for testing the general relativistic…
Joint search for isolated sources and an unresolved confusion background in pulsar timing array data
Bence Bécsy, Neil J. Cornish
Supermassive black hole binaries are the most promising source of gravitational-waves in the frequency band accessible to pulsar timing arrays. Most of these binaries will be too d…
Gravitational-wave versus X-ray tests of strong-field gravity
Alejandro Cardenas-Avendano, Sourabh Nampalliwar, Nicolas Yunes
Electromagnetic observations of the radiation emitted by an accretion disk around a black hole, as well as gravitational wave observations of coalescing binaries, can be used to pr…
Polarization modes of gravitational waves in Quadratic Gravity
Pratik Wagle, Alexander Saffer, Nicolas Yunes
The observation of the inspiral and merger of compact binaries by the LIGO-Virgo collaboration has allowed for new tests of Einstein's theory in the extreme gravity regime, where g…
Data Analysis Implications of Moderately Eccentric Gravitational Waves
Blake Moore, Nicolás Yunes
While the expectation is that the majority of gravitational wave events observable by ground-based detectors will be emitted by compact binaries in quasi-circular orbits, the growi…
Cosmological attractors to general relativity and spontaneous scalarization with disformal coupling
Hector O. Silva, Masato Minamitsuji
The canonical scalar-tensor theory model which exhibits spontaneous scalarization in the strong-gravity regime of neutron stars has long been known to predict a cosmological evolut…
Improved Constraints on Modified Gravity with Eccentric Gravitational Waves
Sizheng Ma, Nicolas Yunes
Recent gravitational wave observations have allowed stringent new constraints on modifications to General Relativity (GR) in the extreme gravity regime. Although these observations…
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…
Noise spectral estimation methods and their impact on gravitational wave measurement of compact binary mergers
Katerina Chatziioannou, Carl-Johan Haster, Tyson B. Littenberg +5
Estimating the parameters of gravitational wave signals detected by ground-based detectors requires an understanding of the properties of the detectors' noise. In particular, the m…
Search for gravitational waves from Scorpius X-1 in the second Advanced LIGO observing run with an improved hidden Markov model
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1134
We present results from a semicoherent search for continuous gravitational waves from the low-mass X-ray binary Scorpius X-1, using a hidden Markov model (HMM) to track spin wander…
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.…
Eikonal quasinormal modes of black holes beyond General Relativity
Kostas Glampedakis, Hector O. Silva
Much of our physical intuition about black hole quasinormal modes in general relativity comes from the eikonal/geometric optics approximation. According to the well-established eik…
More than the sum of its parts: combining parameterized tests of extreme gravity
Hector O. Silva, Nicolás Yunes
We connect two formalisms that describe deformations away from general relativity, one valid in the strong-field regime of neutrons stars and another valid in the radiative regime…
Gravitational Instability of Exotic Compact Objects
Andrea Addazi, Antonino Marciano, Nicolas Yunes
Exotic compact objects with physical surfaces a Planckian distance away from where the horizon would have been are inspired in quantum gravity. Most of these objects are defined by…

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…
Fundamental physics implications on higher-curvature theories from the binary black hole signals in the LIGO-Virgo Catalog GWTC-1
Remya Nair, Scott Perkins, Hector O. Silva +1
Gravitational-wave astronomy offers not only new vistas into the realm of astrophysics, but it also opens an avenue for probing, for the first time, general relativity in its stron…
Constraining alternative polarization states of gravitational waves from individual black hole binaries using pulsar timing arrays
Logan O'Beirne, Neil J. Cornish, Sarah J. Vigeland +1
Pulsar timing arrays are sensitive to gravitational wave perturbations produced by individual supermassive black hole binaries during their early inspiral phase. Modified gravity t…
Self-interactions and Spontaneous Black Hole Scalarization
Caio F. B. Macedo, Jeremy Sakstein, Emanuele Berti +3
It has recently been shown that nontrivial couplings between a scalar and the Gauss-Bonnet invariant can give rise to black hole spontaneous scalarization. Theories that exhibit th…
A 3PN Fourier Domain Waveform for Non-Spinning Binaries with Moderate Eccentricity
Blake Moore, Nicolás Yunes
While current gravitational wave observations with ground based detectors have been consistent with compact binaries in quasi-circular orbits, eccentric binaries may be detectable…
