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…
Nonlinear Relativistic Tidal Response of Neutron Stars
Paolo Pani, Massimiliano Maria Riva, Luca Santoni +2
We investigate the nonlinear tidal response of relativistic neutron stars by computing the fully relativistic, static, quadratic Love numbers. Using both the worldline effective fi…
Vanishing of Quadratic Love Numbers of Schwarzschild Black Holes
Simon Iteanu, Massimiliano Maria Riva, Luca Santoni +2
The induced conservative tidal response of self-gravitating objects in general relativity is parametrized in terms of a set of coefficients, which are commonly referred to as Love…
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…
Vanishing of Nonlinear Tidal Love Numbers of Schwarzschild Black Holes
Massimiliano Maria Riva, Luca Santoni, Nikola Savić +1
It is well known that asymptotically flat Schwarzschild black holes in general relativity in four spacetime dimensions have vanishing induced linear tidal response. We extend this…
Angular momentum balance in gravitational two-body scattering: Flux, memory, and supertranslation invariance
Massimiliano Maria Riva, Filippo Vernizzi, Leong Khim Wong
Two puzzles continue to plague our understanding of angular momentum balance in the context of gravitational two-body scattering. First, because the standard definition of the Bond…
Effective Field Theory for Gravitational Radiation in General Relativity and beyond
Massimiliano Maria Riva
The topic of this thesis is the so-called Non-Relativistic General Relativity, an effective field theory approach proposed by Goldberger and Rothstein to study the conservative and…
Gravitational Bremsstrahlung in the Post-Minkowskian Effective Field Theory
Stavros Mougiakakos, Massimiliano Maria Riva, Filippo Vernizzi
We study the gravitational radiation emitted during the scattering of two spinless bodies in the post-Minkowskian Effective Field Theory approach. We derive the conserved stress-en…
