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…
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…
Gravitational radiation from inspiralling compact binaries to NLO in the Effective Field Theory approach
Loris Amalberti, Zixin Yang, Rafael A. Porto
Within the context of the Effective Field Theory (EFT) framework to gravitational dynamics, we compute the Hamiltonian, source quadrupole moment, and gravitational-wave energy flux…
Signatures of ultralight bosons in the orbital eccentricity of binary black holes
Mateja Bošković, Matthias Koschnitzke, Rafael A. Porto
We show that the existence of clouds of ultralight particles surrounding black holes during their cosmological history as members of a binary system can leave a measurable imprint…
