Dissipation in extreme-mass ratio binaries with a spinning secondary
Sarp Akcay, Sam R. Dolan, Chris Kavanagh +3
We present the gravitational-wave flux balance law in an extreme mass-ratio binary with a spinning secondary. This law relates the flux of energy (angular momentum) radiated to nul…
The location of the last stable orbit in Kerr spacetime
Leo C. Stein, Niels Warburton
Black hole spacetimes, like the Kerr spacetime, admit both stable and plunging orbits, separated in parameter space by the separatrix. Determining the location of the separatrix is…
Unveiling the Gravitational Universe at μ-Hz Frequencies
Alberto Sesana, Natalia Korsakova, Manuel Arca Sedda +31
We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to -Hz frequency range. By the 2040s', the -Hz frequency band, bracketed in…
Probing the Nature of Black Holes: Deep in the mHz Gravitational-Wave Sky
Vishal Baibhav, Leor Barack, Emanuele Berti +26
Black holes are unique among astrophysical sources: they are the simplest macroscopic objects in the Universe, and they are extraordinary in terms of their ability to convert energ…
The Missing Link in Gravitational-Wave Astronomy: Discoveries waiting in the decihertz range
Manuel Arca Sedda, Christopher P. L. Berry, Karan Jani +27
The gravitational-wave astronomical revolution began in 2015 with LIGO's observation of the coalescence of two stellar-mass black holes. Over the coming decades, ground-based detec…
Second-order self-force calculation of the gravitational binding energy in compact binaries
Adam Pound, Barry Wardell, Niels Warburton +1
Self-force theory is the leading method of modeling extreme-mass-ratio inspirals (EMRIs), key sources for the gravitational-wave detector LISA. It is well known that for an accurat…
Factorization and resummation: A new paradigm to improve gravitational wave amplitudes. III: the spinning test-body terms
Alessandro Nagar, Francesco Messina, Chris Kavanagh +4
We present new calculations of the energy flux of a spinning test-body on circular orbits around a Schwarzschild black hole at linear order in the particle spin. We compute the mul…
Gravitational waves from bodies orbiting the Galactic Center black hole and their detectability by LISA
Eric Gourgoulhon, Alexandre Le Tiec, Frederic H. Vincent +1
We present the first fully relativistic study of gravitational radiation from bodies in circular equatorial orbits around the massive black hole at the Galactic Center, Sgr A* and…
