Dynamics of Relativistic Binaries in Structured and Stochastic Environments: A Lagrange-Fourier-Hansen Framework

Lorenz Zwick, Conor Dyson, Brian C. Seymour, János Takátsy et autres

We develop a general framework to characterize non-vacuum perturbations to relativistic binaries in the gravitational-wave (GW) driven regime, for use in GW parameter estimation studies. The effect of smooth, structured and stochastic perturbations to the binary's motion is reduced to a resonant …

Spiral Density Waves and Torque Balance in the Kerr Geometry

Conor Dyson, Daniel J. D'Orazio

Extreme mass-ratio inspirals (EMRIs) in relativistic accretion discs are a key science target for the upcoming LISA mission. Existing models of disc-EMRI interactions typically rely on crude dynamical friction or Newtonian planetary migration prescriptions, which fail to capture the relativistic fluid response …

Waveform modelling for the Laser Interferometer Space Antenna

Niayesh Afshordi, Sarp Akçay, Pau Amaro‐Seoane, Andrea Antonelli et autres

Abstract 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 expand our view to the millihertz gravitational-wave sky, where a spectacular variety of interesting new sources abound: …

Lensing and wave optics in the strong field of a black hole

C. Chan, Conor Dyson, Matilde Garcia, Jaime Redondo–Yuste et autres

Gravitational waves (GWs) are lensed by matter, offering a unique probe of both the large-scale structure of the Universe and the fundamental properties of GW propagation. GWs can also be affected by wave optics effects when their wavelength is comparable to the …

Environmental Effects in Extreme-Mass-Ratio Inspirals: Perturbations to the Environment in Kerr Spacetimes

Conor Dyson, Thomas F. M. Spieksma, Richard Brito, Maarten van de Meent et autres

Future gravitational wave observatories open a unique avenue to study the environments surrounding black holes. Intermediate or extreme mass ratio inspirals will spend thousands to millions of cycles in the sensitivity range of detectors, allowing subtle environmental effects to accumulate in the …

Relativistic aerodynamics of spinning black holes

Conor Dyson, Jaime Redondo–Yuste, Maarten van de Meent, Vítor Cardoso

Astrophysical black holes do not exist in a vacuum, and their motion is affected by the galactic environment. As a black hole moves it attracts stars and matter, creating a wake that, in turn, exerts an effective friction slowing down the black …

Magnetic black holes: From Thomson dipoles to the Penrose process and cosmic censorship

Conor Dyson, David Pereñíguez

We consider accretion of charged test matter by rotating, magnetic black holes and discuss a number of aspects in which the interaction of the angular momentum contained in the electromagnetic field and the spin of the hole plays a fundamental role. First, …
