Shifted-geodesic approximation for spinning-body gravitational wave fluxes
Lisa V. Drummond, Scott A. Hughes, Viktor Skoupý +2
We present a shifted-geodesic framework for computing gravitational-wave fluxes from spinning test bodies moving on bound orbits of Kerr black holes. The method provides a simple a…
Going into a tailspin near the abyss: analytic solutions for spinning particles on near equatorial, plunging orbits in Kerr spacetime
Gabriel Andres Piovano
This work presents, the first time, analytic solutions for the nearly equatorial, plunging motion of a spinning test-particle in Kerr spacetime. The equations of motion are solved…
Spin-aligned inspiral waveforms from self-force and post-Newtonian theory
Loïc Honet, Josh Mathews, Geoffrey Compère +5
We present the state-of-the-art waveform model WaSABI-C for quasicircular inspirals of spinning black hole binaries with aligned or anti-aligned spins. Our model synthesizes the mo…
Particles with precessing spin in Kerr spacetime: analytic solutions for eccentric orbits and homoclinic motion near the equatorial plane
Gabriel Andres Piovano
We present a family of analytic solutions for the nearly-equatorial motion of a test particle with precessing spin in Kerr spacetime. We solve the equations of motion up to linear…
Spherical inspirals of spinning bodies into Kerr black holes
Viktor Skoupý, Gabriel Andres Piovano, Vojtěch Witzany
Extreme mass-ratio inspirals (EMRIs), consisting of a stellar-mass compact object spiraling into a massive black hole, are key sources for future space-based gravitational wave obs…
Spinning particles near Kerr black holes: Orbits and gravitational-wave fluxes through the Hamilton-Jacobi formalism
Gabriel Andres Piovano, Christiana Pantelidou, Jake Mac Uilliam +1
Extreme mass-ratio inspirals are among the key sources of gravitational waves for the Laser Interferometer Space Antenna space-based gravitational-wave detector. Achieving sufficie…
Accuracy Requirements: Assessing the Importance of First Post-Adiabatic Terms for Small-Mass-Ratio Binaries
Ollie Burke, Gabriel Andres Piovano, Niels Warburton +7
We investigate the impact of post-adiabatic (1PA) terms on parameter estimation for extreme and intermediate mass-ratio inspirals using state-of-the-art waveform models. Our analys…
Analytic solutions for the motion of spinning particles near spherically symmetric black holes and exotic compact objects
Vojtěch Witzany, Gabriel Andres Piovano
Rapidly rotating bodies moving in curved space-time experience the so-called spin-curvature force, which becomes important for the motion of compact objects in gravitational-wave i…
Extreme Love in the SPA: constraining the tidal deformability of supermassive objects with extreme mass ratio inspirals and semi-analytical, frequency-domain waveforms
Gabriel Andres Piovano, Andrea Maselli, Paolo Pani
We estimate the accuracy in the measurement of the tidal Love number of a supermassive compact object through the detection of an extreme mass ratio inspiral~(EMRI) by the future L…
Assessing the detectability of the secondary spin in extreme mass-ratio inspirals with fully-relativistic numerical waveforms
Gabriel Andres Piovano, Richard Brito, Andrea Maselli +1
Extreme mass-ratio inspirals~(EMRIs) detectable by the Laser Inteferometric Space Antenna~(LISA) are unique probes of astrophysics and fundamental physics. Parameter estimation for…
Extreme mass ratio inspirals with spinning secondary: a detailed study of equatorial circular motion
Gabriel Andres Piovano, Andrea Maselli, Paolo Pani
Extreme mass-ratio inspirals detectable by the future Laser Interferometer Space Antenna provide a unique way to test general relativity and fundamental physics. Motivated by this…
Model independent tests of the Kerr bound with extreme mass ratio inspirals
Gabriel Andres Piovano, Andrea Maselli, Paolo Pani
An outstanding prediction of general relativity is the fact that the angular momentum of an isolated black hole with mass is limited by the Kerr bound, . Test…
Reheating and Dark Radiation after Fibre Inflation
Michele Cicoli, Gabriel A. Piovano
We study perturbative reheating at the end of fibre inflation where the inflaton is a closed string modulus with a Starobinsky-like potential. We first derive the spectral index $n…
