Second-order Teukolsky calculations for nonspinning, quasicircular binaries
Benjamin Leather, Andrew Spiers, Adam Pound +4
Currently, the only second-order gravitational self-force calculations have been based on directly solving the perturbative Einstein equations in the Lorenz gauge. That method reli…
The significance of first post-adiabatic contributions for scalar charge measurements with intermediate and extreme mass ratio inspirals
Susanna Barsanti, Ollie Burke, Andrea Maselli +3
We present the first self-force-based beyond-GR waveform model incorporating post-adiabatic orbital evolution for intermediate- and extreme-mass-ratio inspirals in theories of grav…
The Bondi--Sachs gauge, BMS frames, and memory in black hole perturbation theory
Andrew Spiers, Adam Pound, Jordan Moxon
As LISA and other next-generation detectors demand increasingly accurate waveform models, there is a growing need for these models to precisely control gauge freedoms that had prev…
Extreme-mass-ratio inspirals in relativistic accretion discs
Francisco Duque, Laura Sberna, Andrew Spiers +1
We compute relativistic Lindblad torques for circular, equatorial extreme-mass-ratio inspirals (EMRIs) embedded in relativistic thin accretion discs, including spinning black hole…
Quadratic quasinormal modes at null infinity on a Schwarzschild spacetime
Patrick Bourg, Rodrigo Panosso Macedo, Andrew Spiers +3
The ringdown of perturbed black holes has been studied since the 1970s, but until recently, studies have focused on linear perturbations. There is now burgeoning interest in nonlin…
Quadratic quasi-normal mode dependence on linear mode parity
Patrick Bourg, Rodrigo Panosso Macedo, Andrew Spiers +3
Quasinormal modes (QNMs) uniquely describe the dominant piece of the gravitational-wave ringdown of postmerger black holes. While the linear QNM regime has been extensively studied…
Analytically Separating the Source of the Teukolsky Equation
Andrew Spiers
Recent gravitational wave detections from black hole mergers have underscored the critical role black hole perturbation theory and the Teukolsky equation play in understanding the…
Ringdowns for black holes with scalar hair: the large mass case
Giovanni D'Addario, Antonio Padilla, Paul M. Saffin +2
Deviations from General Relativity can alter the quasi-normal mode (QNM) ringdown of perturbed black holes. It is known that a shift-symmetric (hence massless) scalar can only intr…
Waveform Modelling for the Laser Interferometer Space Antenna
LISA Consortium Waveform Working Group, Niayesh Afshordi, Sarp Akçay +144
LISA, the Laser Interferometer Space Antenna, will usher in a new era in gravitational-wave astronomy. As the first anticipated space-based gravitational-wave detector, it will exp…
Measuring scalar charge with compact binaries: High accuracy modelling with self-force
Andrew Spiers, Andrea Maselli, Thomas P. Sotiriou
Using the self-force approach, we present the premier first-post-adiabatic accuracy formalism for modelling compact binaries in theories with a massless scalar field non-minimally…
