Separability of the motion of spinning test particles in curved space-time

Vojtěch Witzany, Viktor Skoupý

Solving for the motion of spinning test particles in curved spacetimes is important for modeling gravitational-wave inspirals of spinning compact binaries. We build a Hamiltonian f…

Toward relativistic inspirals into black holes surrounded by matter

Lukáš Polcar, Vojtěch Witzany

Extreme mass ratio inspirals, compact objects spiraling into massive black holes, represent key sources for future space-based gravitational-wave detectors such as LISA. The inspir…

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…

Alive and Strongly Kicking: Stable X-ray Quasi-Periodic Eruptions from eRO-QPE2 over 3.5 Years

Dheeraj Pasham, Shubham Kejriwal, Eric Coughlin +5

Quasi-periodic eruptions (QPEs) are recurring bursts of soft X-rays from the nuclei of galaxies. Their physical origin is currently a subject of debate, with models typically invok…

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…

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…
