Tests of general relativity with gravitational-wave observations using a flexible theory-independent method Open
We perform tests of general relativity (GR) with gravitational waves (GWs) from the inspiral stage of compact binaries using a theory-independent framework, which adds generic phase corrections to each multipole of a GR waveform model in f…

PROBING FUNDAMENTAL PHYSICS WITH GRAVITATIONAL WAVES FROM INSPIRALING BINARY SYSTEMS Open
The mergers of black holes and/or neutron stars in binary systems produce the most extreme gravitational environments in the local universe. The first direct detections of gravitational waves by Advanced LIGO and Virgo provide unprecedente…

Gravitational-wave constraints on an effective-field-theory extension of general relativity Open
Gravitational-wave observations of coalescing binary systems allow for novel tests of the strong-field regime of gravity. Using data from the Gravitational Wave Open Science Center (GWOSC) of the LIGO and Virgo detectors, we place the firs…

Theory-agnostic framework for dynamical scalarization of compact binaries Open
Gravitational wave observations can provide unprecedented insight into the\nfundamental nature of gravity and allow for novel tests of modifications to\nGeneral Relativity. One proposed modification suggests that gravity may undergo\na pha…

Hairy binary black holes in Einstein-Maxwell-dilaton theory and their effective-one-body description Open
In General Relativity and many modified theories of gravity, isolated black\nholes (BHs) cannot source massless scalar fields. Einstein-Maxwell-dilaton\n(EMd) theory is an exception: through couplings both to electromagnetism and\n(non-min…

Constraining Nonperturbative Strong-Field Effects in Scalar-Tensor Gravity by Combining Pulsar Timing and Laser-Interferometer Gravitational-Wave Detectors Open
Pulsar timing and gravitational-wave (GW) detectors are superb laboratories\nto study gravity theories in the strong-field regime. Here we combine those\ntools to test the mono-scalar-tensor theory of Damour and Esposito-Far{\\`e}se\n(DEF)…

Effective action model of dynamically scalarizing binary neutron stars Open
Gravitational waves can be used to test general relativity (GR) in the highly\ndynamical strong-field regime. Scalar-tensor theories of gravity are natural\nalternatives to GR that can manifest nonperturbative phenomena in neutron stars\n(…

Distinguishing boson stars from black holes and neutron stars from tidal interactions in inspiraling binary systems Open
Binary systems containing boson stars---self-gravitating configurations of a complex scalar field--- can potentially mimic black holes or neutron stars as gravitational-wave sources. We investigate the extent to which tidal effects in the …

Gravitational waveforms in scalar-tensor gravity at 2PN relative order Open
We compute the gravitational waveform from a binary system in scalar-tensor\ngravity at 2PN relative order. We restrict our calculation to non-spinning\nbinary systems on quasi-circular orbits and compute the spin-weighted spherical\nmodes…

Modeling dynamical scalarization with a resummed post-Newtonian expansion Open
Despite stringent constraints set by astrophysical observations, there remain\nviable scalar-tensor theories that could be distinguished from general\nrelativity with gravitational-wave detectors. A promising signal predicted in\nthese alt…
