Nonlocal-in-time tail effects in gravitational scattering to fifth Post-Minkowskian and tenth self-force orders

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

Using the worldline effective field theory formalism, we derive the nonlocal-in-time conservative contributions arising from tail effects in gravitational scattering to fifth Post-…

Black Hole Dynamics at Fifth Post-Newtonian Order

Rafael A. Porto, Massimiliano M. Riva

Using the worldline action in [2409.05860], we derive the total even-in-velocity (relative) impulse, scattering angle, and time delay at fifth post-Newtonian (5PN) order, including…

Trails of clouds in binary black holes

Mateja Bošković, Rafael A. Porto, Matthias Koschnitzke

Superradiant instabilities of rotating black holes can give rise to long-lived bosonic clouds, offering natural laboratories to probe ultralight particles across a wide range of pa…

The Science of the Einstein Telescope

Adrian Abac, Raul Abramo, Simone Albanesi +485

Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…

Local-in-Time Conservative Binary Dynamics at Fifth Post-Minkowskian and First Self-Force Orders

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

We report the local-in-time conservative dynamics of nonspinning binary systems at fifth Post-Minkowskian (5PM) and first self-force (1SF) orders. This follows from an explicit cal…

Nonlinear Gravitational Radiation Reaction: Failed Tail, Memories & Squares

Rafael A. Porto, Massimiliano M. Riva, Zixin Yang

Using the Schwinger-Keldysh "in-in" effective field theory (EFT) framework, we complete the knowledge of nonlinear gravitational radiation-reaction effects in the (relative) dynami…
